how to check the number of thread? on my ? Apache server? ,? is there a specific command , and how do i increase these threads ..

If you are talking about worker threads. Turn on server-status in the httpd.conf (make sure security is set correctly), and check http://serverip/server-status.

Slightly OT .... FWIW ....

One quick-and-dirty way to check threads for any process is to use the ncurses-based 'htop' utility. I much prefer this to 'top' for several reasons, including its ability to hide/display kernel threads, hide/display user threads (in a different color if you like), display with vertical and horizontal scrolling, assign processor affinity on the fly, ptrace/strace processes, and a lot more.

It's in Dag Wieers' rpmforge repository for CentOS.

The suggestions offered in this discussion are all very useful with regard to tuning Apache.
