Hi. I have occasional very high load on my server. Do you have any ideas what could be the problem? The ps aux shot was taken on 2006-11-13 at 15:49:40. The interesting thing is that most of the postfix and procmail, perl processes hangs there from 15:38. But they dissapear after while and server load goes down again. At the time of high load server has big problems to serve its users. Code: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND www-data 15376 0.0 1.6 109256 4992 ?

I seem to be having the same problem. Any remedy? I don't get that many emails. I only have less than 5 email accounts on that server. And perhaps less than 2 spams/day all together.
