I am running a program that users can connect to and chat with but for some strange reason I cannot get more than 1019 users in the hub.

When the hub is full of users I get a disconnected message which tells me that the TCP/IP Stack is rejecting my connection.

Any ideas what to check because it runs fine on FreeBSD (apart from the crashes every few hours - BSD problem not the software )

Anything I can look for


Btw... the software is running as root on port 3124

What is your network card, I will begin to search from that for my part.

Interesting question. I can't remember ..... it's a server on a server farm. I am only able to connect via SSH to manage it.

Anyway I can find out ?

And I know the server has had over 7000 connections when it was running windowsXP Pro ....

Anything else i can do ?

Any help to you ?

Fixed problem with ULIMIT -N 4096 command

I believe this a kernel option. have a look at your config.

Just a FYI you should be using #setrlimit instead of ulimit assuming you are using the newest version of glibc

Got no setrlimit command on my server

Also how do i check glibc version ??

Not trying to be stupid .... but i'm having to learn linux all again and this is a hosted server that i control remotely.

Any help will be apprexciated

try to run :
/lib/libc-*.so

That's what i get out of it

Anything else to check ?

My apologies I read your post incorrectly. the setrlimit is used for programming you used the correct command from the prompt. I thought you where writing a program that used multiple resource limits.

I'm having a problem whereby i'm limited to 4065 users now.

I'm gonna move this thread into a different section to see if I can get more widespread help.

Many thanks to all that posted replies
