Hello.
Recently, I noticed that when a certain number of httpd processes are reached, the Apache begins to hang. There are enough resources, the Apache does not fall. Just hanging. I did not make any changes in the configuration (only after the appearance of the problem I increased the limits, as a result, the processes increased, but it also hangs).
I rebooted both the apache himself and the entire server.
What could be wrong?
All on CentOS 5.
