Media Server :: Crashing On CentOS?
Jan 8, 2010
I just upgraded one of our servers running FMS 3.0 to FMS 3.5.3 but it causes a sudden spike in server load causing the server to crash.I managed to see an error after I tried to stop FMS during one of its server load spikes:
NPTL 2.3.4Stopping Adobe Flash Media Server (please check /var/log/messages)*** glibc detected *** double free or corruption (fasttop): 0xf3a21ef0 ***
FMS 3.0 worked fine on this server with the exception of the admin server crashing once in a while. We have FMS 3.5.2 running on another CentOS server without any issues. We're now hesitant to upgrade other servers to FMS 3.5.3 until we hear back from Adobe on this issue.
P.S: This server is live and very active so it's possible that playback of a live or VOD stream is causing these crashes because they started happening after we turned it on for customers. It didn't seem to crash when it was running on its own with some local testing.

I'm trying different subversions of FMS 3.5 on CentOS 5.5 ;I tried :
FMS 3.5.1 on CentOS 5.5 64 bits (3.5.2 and 3.5.3 not working, libraries problems)
FMS 3.5.3 on CentOS 5.5 32 bits
FMS 3.5.4 on CentOS 5.5 (fmsadmin illegal instruction) See post http://forums.adobe.com/thread/715650
On 3.5.1 and 3.5.3, the server works well many hours / day, but sometimes the FMS service and the server crashes (tested on 2 servers) ;The only thing i can see in logs is in the /opt/adobe/fms/logs/access.XX.log files and looks like this :
^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@
[code]....
There is something i can do to prevent my server from crashing ? I will try the release 3.5.0 which works well on Gentoo distrib ... but i would like to use last versions of the server.

FMS is crashing with the following errors:

Consider increasing the heap size to prevent future memory allocation failures. -2011-12-06 10:24:02 12461 (w)2581227 Shared memory heap (__FCS__) has exceeded 90 usage.

Consider increasing the heap size to prevent future memory allocation failures. -
When I try to restart I get:
2011-12-06 17:33:27 7933(e)2781340 Process 7933 failed to create IPC queue __FCS__ : Failed to allocate shared memory. - I've noticed the problem resolves when I restart fmsadmin. I think fmsadmin is using up all the shared memory, not sure. There are HTTP requests periodically being sent to fmsadmin, could this be a source of memory leak?
The server has 6 GB RAM and there are only about 100-200 connections being used. Runs without issues most of the time, crashes once every few days.What is the shared memory heap and how do I increase it?

I'm trying to troubleshoot a Flash Media Server working with a little video playback application I wrote a few years ago that has suddenly stopped working.I'm using CS3/Actionscript 3.My app uses the FLVPlayback Component, and was working well last time I checked. I recevied a report that the videos stopped working, and have been looking into it.I figured I'd add a bunch of event listeners to the FLVPlayback's ncMgr.netConnection so I could get debug info on things like io errors, net status, etc.The problem I'm running into is that the netConnection is null when I set it to anything on my Flash Media Server, and adding any event listeners to this netConnection throws errors.Here's what I've tried so far:
Playback of a local FLV file works fine.In the FLVPlayback documentation, I found an example and stole the URL of the stream they were using in the example, and that works fine, although it is an HTTP protocol stream rather than RTMP.Any attempt to access FLV files on my Media Server, which has worked fine in the past, basically cause the FLVPlayback object to sit and hang in "buffering" mode and never progresses beyond this point.The netConnection object in this case is null.Here's my code:[code]........
Again the purpose of this is to troubleshoot the video streaming from the Flash Media Server, and it seems like there is no netconnection to the server being created.Does this mean that the server is not working, or is there a problem with the way I'm trying to access the content on the server?This was all working fine before, and I have set up the server-side application .ASC files and such to allow things to work fine on the server end.

I'm trying to make a software which sends video and audio data to a flash media server by using RTMP protocol. Currently, my program can communicate with a flash media server correctly. RTMP specifications does not describe about the raw data in video/audio messages, so I muxed raw H.264 and AAC data into video/audio messages and sent to the server. The server seems to accept them, but a video player cannot playback the stream sending from the server. The player just says "Loading..." For a test purpose, I sniffed the network packets between Wirecast and the flash media server and ripped off only video and audio data. Then, I muxed those data into video/audio message and sent to the flash media server. In this case, the video player connected to the server can playback the stream correctly.
I checked the stream sent from Wirecast, the stream seems not to be H.264 raw data because those data are not started from 0x17 instead of H.264 start code. With those situation, I am wondering what kind of container format I should use for H.264/AAC data to the flash media server.

I have Flash Media Streaming Server 3.5 (not Interactive) running on RHEL5.5 x86_64 Linux.All is working well, however how do I prevent unauthorized access to connecting to the live stream and streaming content?How can I setup the server to require a user and password to stream live media to the server?I am new to this product and I have been reading some documentation but I have not found a clear cut answer on how to force a username and password to connect to the server to stream live content only.I am using the Adobe FMS Apache install, what files need changing?[code]I want to lock down a person from connecting to the server on the public internet and starting a live stream?Can this be done with a user name and password?

We purchased FMIS and we are encoding large 15+ hour MP4 recordings using flash media encoder. When opening these large files for playback, which have not been opened recently the player displays the loading indicator for up to 4 minutes! Once it has apparently been cached on the server it opens immediately from any browser even after clearing local browser cache. So a few questions for the experts
1. Why is it taking so long to load the file. Is it because the MP4 metadata is in the wrong format and the file is so huge? I read somewhere that Media Encoder records with incorrect MP4 metadata is that still the case?
2. Once its cached on the server, exactly how much of it is cached. Some of these files are larger than 500mb.
3. What fms settings do you suggest I change. FMIS is running on windows server R2 64 bit, but FMIS itself is 32 bit. We have not upgraded to the 64 bit version. We have 8GB of ram. Is it OK to set FMS cache to 3GB. And would that only have enough room for 3-4 large files, because we have hundreds of them.

I'm building a video conferencing applicaition for a portal. But now when considering which version of flash media server to buy, I run into some problem. So can anyone helps me about comparing this two versions: Flash Media Streaming Server and Flash Media Interactive server, like if I use Flash Media Streaming Server, some function like NetStream.pause() may not work or something like that? I'm not sure if this is a foolish question but please let me know.

I'm running Flash Media Streaming Server and have only been serving VOD up until now. I had my network administrator open up port 1935 to the outside world during the setup process and now I can't remember if that was actually required for streaming VOD to clients. Most documentation I've read says that this port should be open, but I seem to recall reading something at one point that suggested it wasn't necessary.
I've just started messing around with publishing live streams using Flash Media Live Encoder to the Flash Media Streaming Server. I have that working without issue but was surprised to find that no authentication is required before a client running the live encoder can publish a stream to the Flash Media Streaming Server. An authentication module is available however it only works with Flash Media Interactive Server and Flash Media Development Server.
If I leave port 1935 open to the outside world, there would be nothing to stop anybody anywhere from streaming video via my server. Anyone else running a default install of Flash Media Streaming Server and with port 1935 open to the outside should see that this is true of their setup as well. I'm wondering if I can safely close port 1935 without limiting the functionality of the server or if there's some way I can require authentication prior to publishing a live stream even though I'm not on the four-and-a-half-times-more-expensive edition of the product.

I need urgently to build simple streaming live video web application.i need to create some live video streams from webcamin one computer through my server to webcam in another computer is Adobe Flash Media Streaming Server is able to do it or only Adobe Flash Media Interactive Server is able to do it?if Adobe Flash Media Streaming Server is able to deal with live video streams is there any major difference between them like for example is it possible to record live video streams in Media Streaming Server? The only clear difference between them is the price.I can afford baying the Media Streaming Server bat not the Media Interactive Server and i need to decide before i am turning to other very less quality java based solutions.

We will only use the servers for Live streaming and VoDs, so far no plan for any complex applications to be deployed on the servers yet. As
far as I understand, the bottleneck of streaming servers are with network connection rather than CPU or resources (servers are only support up to 4GB of RAM anyway).

I want to record a stream which is published with Flash Live Encoder to FMS 3.5, but split the recording in files with predefined length. For example if a stream 'webcam' is published I want to record it in chunks of 10 minutes: 'webcam1.flv', 'webcam2.flv' ... From what I can tell there's no facility to work with timers. The only solution I could think of was using stream.record() with a time limit parameter but that seems like a hack because it triggerstStream.Record.DiskQuotaExceeded on the stream when the recordin should stop and start recording another chunk. Has anyone done something similar?

I would like to ask if Adobe Flash Media Streaming Server (not Interactive) supports the following Stream.play (server-side streaming), but not necessarily server-side playlists which I know is a FMIS featureunsigned server-side asctionscripts (main.asc) The difference is in the price of course, one is $1000, the other is $5000, so if the two above are supported, I will buy FMSS

I evaluated the Flash Media Server 3.5 by running samples for .flv,f4v,.mpg,.avi video formats and the product looks excellent to work as a Video Streaming Server - Live Video, Recorded Video Viewing by Audiences.
Query : ELearning Course modules are designed and developed using Macromedia Flash and Action Scripting Language.The Output Formats of the LMS are .swf files.As Elearning courses - LMS offer/involves User Interaction (Viewing courses by Students, Giving Exams for obtaining certification etc).Can we also use the Flash Media Server 3.5 for integrating with LMS Site running in IIS 6.0/7.0 ?
Client : IE 6.0/7.0, Macromedia Flash Player 10.0.
