Also I've noticed that every time when average server load is growing number of active APACHE a processes is also growing. For example if I do 'netstat -anpl | grep STREAM | grep apache' to get number of active UNIX domain sockets (servers and established) with apache I got 5 apaches when average server load is 5 and 1-2 apaches when load average is quite small.
Then if I grep netstat for PID of these apaches above I see connections to my IMAP server with CLOSE_WAIT state. Thanks.
