maximum concurrent connections for ubuntu?

开发者_开发技巧i would like to ask how many concurrent connections can ubuntu handle? i heard that xp a maximum of 10 connections.. i will use it as an OS for my small server and will be using mysql on it..

You are probably making all of the tcp connections from one process and hitting the default limit on number of open files per process. You can confirm that limit with 'ulimit -a' or 'ulimit -n' at a shell prompt. You could increase that limit with 'ulimit -n ' or setrlimit() as root or by editing /etc/security/limits.conf .
