Media Server :: Closes Connections And Rejects New Connections?
Feb 23, 2012
I have been running FMIS 3.5 for about 18 months, and recently it started acting up even though I have not made any changes. After a while (sometimes days, sometimes hours), it starts rejecting new connections, but it allows existing connections to keep working. If I refresh my app, then I can't reconnect. The license I have is unlimited. Can anyone shed some light into why this is doing this and what I can do to fix it? Sometimes it happens when only a couple dozen people are online, and today it did it about 4 times with over 1500 people online.
The attached image shows 17 client connections. Unfortunately there are not 17 clients connected to that app. In fact, I add users to a userlist shared object in application.onConnect(), and that shared object only reports 6 connections. That is the accurate number of connected users.
Why the phantom connections? Even if I unload and reload the app, the 17 client connections return.
How can my userlist shared object and the client connection number be out of sync? This situation seems to be related in some way to an FMS memory problem that is cropping up all of a sudden. When I have larger numbers of connected clients - say 300, the client connections reported in the FMS console are ten times that - like 3,000 or more. Then the application is unloaded by FMS for being a memory hog.
The app itself is simple. It just stores each user in a user array and passes chat communication to and from these users. The last time this main.asc code was changed was 2/8/2010. No problems with it in the countless times we've used it since then. Why the sudden phantom FMS connections, memory hog behavior, and constant unloading of the app?
URL...I am running application instance that implements publisher/subscriber on video streams. Application code is very thin and can be removed completetly if required. In a specific time, randomly, disconnect messages stopped happening which causes the folowing:
1. Streaming service shows decrease of bw per second
I have FMS 4 and a videochat app (one-to-one), everything runs smoothly until about 750 users (it means about 1500 connections to fms), then I get a sudden drop in users connected to 300-400, no errors in the fms log and the cpu/memory usage is at about 25% just before this. I'm running Windows 2008 R2 Web (x64) and I've red somewhere that maybe this version of windows has some connection limit that could be the cause, but I've no idea of what could be happening.
I have a FMS server running that I am hosting some VOD content on. I am using HTTP dynamic streaming to deliver this content. Everything runs fine from a technical standpoint, but I am unable to see the connection details in the Admin Console. I have loaded vod -> defaultinst under the applications tab in the console. No connection details populate.
I'd like to hear some opinions about using NetGroups VS. using direct p2p connections between everybody, considering there would either be 2,3 or 4 people max in the group.
I have a setup where I have some edge servers (as in <Mode>remote</Mode>) that pull content from an origin server. I only want to allow RTMPE connections to the edge server. I'm trying to do this by using the <DisallowedProtocols> element on the origin server. I'm setting: <DisallowedProtocols>rtmp,rtmps,rtmpt</DisallowedProtocols>
in the relevant Vhost.xml on the origin server. However, when I do that, proxying through the edge server stops working. I get a "Connection attempt rejected by FMS server [ Server.Reject ] : Connection failed." from OSMFPlayer (which I'm using for testing) and these lines show up on the origin server's core.00.log file:
Does FMS 3.5.2 in development impose restrictions via the origin of connections? That is, does it only allow localhost connections via ActionScript (NetConnection) or are external connections allowed?In other words, can I have FMS in dev mode on a dedicated server and then have my client code running on a different machine that opens connections to this development server?
In multiple instances, limiting the maximum number of connections for the same IP?You give me the answer is to limit a single instance, whether there is a way to limit the number of users of the entire connected to the FMS?
We have a custom application that is running on FMS. Server is dedicated just for fms, there is only one application running on the server, with more instances, average traffic is 3-15 simultaneous users.The problem is,server suddenly stops accepting connections (after 1-3 days from restart), from this point it is impossible to connect to any instance, and fms server must be restarted.When the server crashes, the admin console can see all open instances, can close instances, can restart fms. There is nothing logged, that would explain this sudden failure.Second problem is, cores are connected and disconnected too often, causing client to reconnect (takes 2-5 seconds).
Hardware: 4 x quadcore Intel(R) Xeon(R) CPU E7440 @ 2.40GHz, 32 GB ram OS: CentOS release 5.3 (Final), kernel: 2.6.18-128.4.1.el5 cpu and mem usage: 1-5% max[code]...........
2 x Intel(R) Xeon(R) CPU L5410 @ 2.33GHz 16Gb RAM 2 Gbit ethernet channel OS - Linux CentOS 5.5 x86_64 FMS4 Interactive
Live stream parameters:
320Ñ…240 qua_=87 bw_=200000 kf_=5 fps_=18
So, after approximately 600 connections to one stream video becomes choppy (periodically freeze, slow motions). CPU-usage at this time is 100-120% (maximum is 800%, 100% per each core), network usage is 500 Mbit/sec.But second live stream(with few connections) at this server looks fine simultaneously with 600 connections at first stream.Experiments with recommendation in "Configuring performance features" documentation chapter(enabling/disabling aggregate messages and configure the size of stream chunks) do not help.
I've been trying to figure out FMS for about a week now. Because of company firewalls, all traffic must go through either port 80 or 443 (I configured this in FMS.ini). I also created a self-signed SSL certificate and configured the adaptor.xml file to use it. Nevertheless, here are the problems I am experiencing: For RTMPT & RTMPTE, I can't start more than 9 connections. Beforing configuring FMS to also use port 443, I could only get about 4 connections. Now I would like to say that I testing this between only two computers, the FMS server with apache web server and a client.why it will not at least start 10 connections which I know is the limit for the dev version? Also, when using RTMPS I can only start 1 connection. Why is that?
It stands to reason that an OS would have a memory limit for the FMS process. I have a video chat app to which I may need to connect 300,000 or more concurrent users. Has anyone done this? Would this break the bank? What's the most you've ever had connected at once?
The video portion of my app goes through a good CDN, so I don't think there's a problem there. But my chat room is all on one FMS instance. I see something in FMS docs in "configuring performance features" that warns, "Adobe recommends that you ensure that your total system memory usage does not exceed the process limit of your OS". Granted it's in the context of configuring media cache, but wouldn't the same apply to chat room size if the numbers get high enough?
I am involved in project managment for a large video conferncing project involving over 100k simultanous connection and most likely to be increased 4 times by next six months.While figuring out the scalability area ,it was concluded that smart selection of hardware and origin-edge clustering will be suited most. Well while studying this documentation says it supports thousands of calls but unfortunately I could not determine the actual numbers. Can you tell me how many edge server will be needed for 100k simultanous calls/number of sessions per edge server and will we need license (4500$) for each edge server?
I have made a socket server in C# for a flash game that I am developing, I got the code from somewhere and I am a beginner in c# and .net development . It works fine in practice when connections are made and the server functions correctly. Get 2 concurrent connections at the same time and we have a problem. here is the basic aspects of the socket server below: (alot taken out for obvious reasons) how can I alter this so that it can handle concurrent connections? Should I be threading each response?
I am willing to make an online game client-server. That is, many clients are connected on the same server, and thus interact. The application used by clients is a swf (done in flash) and runs in a browser. My questions are: 1 - I can create the server in AIR? If yes, which of the classes are recommended to do this efficiently? 2 - What classes are recommended for clients (swfs) to communicate with the server efficiently? 3 - The transfer of data between the client and the server can only be accomplished through the TCP protocol?
We have a flex application communicating with our server. The flex app makes many HTTP requests (posts and gets) to the server, in many cases in parallel. We have been noticing that we get many dropped connections, experienced from the flex app. The server does not see any failed requests at all and is not under load. I am also suspecting that flex may be on-connection-drop, automatically retrying the POST or GET request, resulting in our server receiving the request twice.
How do I set the flash crossdomain.xml file to only allow https ssl secured connections? I have this but I think this will allow non secure connections too.
I am trying to debug a socket connection issue between flash in a web browser and flash in a client type program. The connection is closing properly in the web, so I would like to understand how the web side of things work. Right now I can load up a remote flash file in a web browser and that triggers a connection ESTABLISHED stat when viewing with netstats -fn. When I close the dialog which runs some javascript to remove the flash from the dom, the connection stats goes to TIME_WAIT. Does the act of removing the flash from the html DOM sever the flash connection which triggers a TIME_WAIT state? How does that process work?
i wanted to make a game in which you play head to head with other people.. but before i get ahead of myself here..how to establish a server which receives info from all connected flash movies , and then sends it out to all the ones witch i want to? basically i was thinking of making a chat thing 1st of all and then depending on how difficult it is move on to my game idea..
is it possible to write a class just to connect to the SQLite database? As in, writing the class, and calling it in another class, so that I don't have to type everything out everytime I need to connect to the database.
i wanted to make a game in which you play head to head with other people.. but before i get ahead of myself here..Any tutorials on how to establish a server which receives info from all connected flash movies , and then sends it out to all the ones witch i want to?basically i was thinking of making a chat thing 1st of all and then depending on how difficult it is move on to my game idea..
I'm working on a game and want the freedom to choose between UDP and TCP connections in the future when I decide to add multiplayer. I'm not sure how something like this would work in the browser with security.
There are two scenarios I can think of for multiplayer. The first is that a player becomes the host of the game (in the browser) and thus would need to communicate with other players directly via TCP or UDP. This would save me on bandwidth costs.
The second scenario would be to have the web server host the game and pass messages back and forth to the clients again via TCP or UDP.
Do Flash or Java applets let me do something like this? If not is there an alternative I can use for the browser or am I stuck with moving to providing a game download and installation?
I am using Wowza Media Server's webcam record capability in a project. It records the webcam feed over RTMP which is connected to via a flash file. It's all working fine, but I need to stress/load test the functionality to check how it'll scale up.
I'm trying to include a database un flex4 (flashbuilder) project, I don't see data and SQL packages in the import? What might be the reason? Should I add external library?
