Hi,
I got a message from my load monitoring script... one of our ispconfig server has a unusual high load since round about 30 minutes…
Code:
29296 username 25 0 63924 35m 29m R 22.3 1.7 0:00.67 spamassassin
29320 username 25 0 20216 13m 7040 R 17.6 0.7 0:00.53 clamscan
It's a Athlon X2 4200 CPU with 2GB RAM… so I think it's not „a matter of size“…
Code:
top - 16:30:22 up 19 days, 57 min, 1 user, load average: 3.81, 3.72, 3.32

Looks like a process is stuck… (<defunct>)
Code:
# ps waux | grep username

A few minutes later it's working fine…

So… any ideas what's going on there?
