RTMPT connection closes with Red5 after some time

I am using Red5 version 1.0.0(final release) for Java 6 on Windows XP sp3.I am using the installer version downloaded from https://code.google.com/p/red5/. I have a project wherein I am performing live webcam chats between the users. I am using RTMPT (HTTP over RTMP)protocol for that.So I have set up my Red5 server behind the Apache web server.The problem is that everything goes on well for 45-50 seconds and suddenly the RTMPT connection gets closed.I am not using a dedicated rtmpt server,i.e. I have not uncommented the rtmpt bean in the conf files.Rather I have added entries of servlet mappings(for idle,fcs,open etc) in the web.xml of my application. RTMPT is listening on 5080 port.I have tested this with previous versions of Red5 also but the problem is the same.The RTMPT connection closes after some time(within a minute).I had gone through logs but there was found nothing regarding this.Also there was no connection closure due to the inactivity period.Has it something to do with Apache? I am not sure whether server is closing the connection (though I cant find any logs about closing connection) or client closes it.Tried it out with 0.9.0 and 0.9.1 too but nothing to avail.I have heard that there were issues using RTMPT with Red5 on Mac but I am on Windows.Any pointers to this problem? Any help is appreciated.Also here are the error logs that I get on my Apache web server -

[error] (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : proxy: HTTP: attempt to connect to red5serverip:5080 (*) failed.

The same log is repeated for four times.

Here are some access logs from Apache too -

"POST /send/IDTK7NOG2PXGB/803 HTTP/1.1" 200 1
"POST /send/IDTK7NOG2PXGB/804 HTTP/1.1" 503 323
"POST /send/YXF4WTFMN8TCM/1391 HTTP/1.1" 200 8285
"POST /send/YXF4WTFMN8TCM/1392 HTTP/1.1" 200 1
"POST /send/YXF4WTFMN8TCM/1393 HTTP/1.1" 200 54
"POST /send/YXF4WTFMN8TCM/1394 HTTP/1.1" 200 1
"POST /send/YXF4WTFMN8TCM/1395 HTTP/1.1" 503 323
"POST /close/IDTK7NOG2PXGB/805 HTTP/1.1" 503 323
"POST /close/YXF4WTFMN8TCM/1396 HTTP/1.1" 503 323

Thanx!

The 503 means that the service did not respond; if you are forwarding to red5 via apache, then this means there is a problem there. I would suggest not using the stand alone rtmpt bean; instead use only the servlet and remove apache from the mix to debug the issue.

Your red5 server may be crashed. This occurs when your RAM usage is getting over. In that case you need to manually start red5 again. If this solved your problem, you need to upgrade your RAM. I am using about 8GB RAM after facing this problem several times. Because red5 was written using JAVA, it lacks memory. FFMPEG is good to use in a low memory. But I don't know how to provide chat using ffmpeg, exactly.

Probably you are running out of tcp ports. A tcp connection will remain 4 minutes in the TIME_WAIT state by default, even if it is already closed. When your RTMPT stream uses 5 connections each second, your system will need at least 5*60*4=1200 ports for each connected user.

Often the firewall is limiting the amount of ports available. You can also decrease the keep-alive time of a tcp socket. If you google around with your apache error message you will find enough info to sort this out.
