java.net.SocketException: Too many open files
Hm, maybe your operating system has somekind of limit for opened files per application.

P.S.: Please don’t write thread titles in capital letters.

Thanks Martin,

We increase ulimit -n size in Linux system and our load test passes smoothly in Http-Bind with 5000 users on two diffrent server with server to server. There is 2% session droped rate. The load is equally divided on the two servers.

Sorry for Writing Thread title in capital letters. I will remember in future. Thanks for help.
