Hello, sorry for my bad english. I've a strange problem with my flashchat realized on php and xmlsocket. I premise that chat works fine with 100 concurrent user. But When the number rises, and I've been to 350 users at the same time, something happens to the server which makes the whole thing freeze. After I eliminated just about everything that can go wrong with the php side of things, we came to the conclusion that this must be something related to the apache, since if before the php socket server went bad on account of an error, we simply needed to relaunch the php again, and everything would start up and work just fine untill the next crash. We have a unix server, using Apache 2, php 4.something or 5 (but again, problem is not there), did anyone knows what this could be? are we passing some limit of sockets connections Apache has that we don't know about? a limit of data transfer we are breaking? my script, when running and holding on to 300 users, use about 2-3 Mbit of bandwidth, nothing to get excited about. Can some one help?!! Thanks.

What is the kind of memory and cpu usage when flashchat reaches its peak values. Probably the server is running our of memory

None. Memory 300mb on 2GB, CPU 5%, Load Average: 0.10 The server is new, dual core, apache2, 2 GB of RAM. There isn't nothing, only the socket. Thanks

you might need to modify your php settings and optimize php with your application.

I made a new test and unfortunately the results are always the same The script is go down with 275 concurrancy users. Strange, because the server was not having load.
