Media Server :: FMS Seems To Stop Returning Data?

I'm currently working as part of team of developers and we've run into an issue with our FMS project.In our site the user is able to record video of themselves which is turned into flvs and stored by the FMS. These videos are played back at a later time. The site works fine but intermittently stops recording new videos or streaming previously recorded videos.The only solution at this point is to restart the server. The server logs show that the onDisconnect event handler is running when users terminate their sessions and we can see that the number of active connections does not appear to be exceeding the limit on the server. There are no runtime errors to indicate that anything has gone wrong.From looking at output from the app it just seems like the publish and unpublish event handlers stop running but nothing actually breaks.The user doesn't realize anything is wrong until they try to watch their videos only to get a blank screen.

We're wondering if perhaps it is a garbage collection issue? Either the garbage collector in the FMS is running and taking a really long time to reload the app or perhaps it isn't running at all and somewhere some memory is overloading.
