ISPsystem.com Forums - Apache Log!

In last two days my server is a little bit slower, some pages doesn't open completely. I found something very strange in httpd log.

Code:

Parameter "23 total children" sometimes goes to 50 and above. What all this means, is this some kind of attack or something similar. None of the configuration wasn't changed. This is server with 50 domains!

Server is CentOS Linux with Apache 2.2.3

Any ideas!!

Thanks!!!
