jboss “Too many open files” 错误

现象：1）jboss java进程能起来，log 显示“Too many open files”错误

　　   2）网站无法访问，重启也无效

解决：

I had this problem also (on linux). What I did:

1. Check limits : ulimit -a
2. check 2 lines in output:

    open files                      (-n) 1024
    max user processes              (-u) 1024

Set both parameters ( for example in your .bash_profile  eg: /etc/profile)

    ulimit -SHn 100000
    ulimit -SHu 100000

In my case I had to change both parameters to solve the problem.
