Qmail and Plesk 11

New Pleskian
Hi guys,

We're running Centos 5.9 with Plesk 11 and Qmail - we have weird issues with the qmail-queue processes using up 100% cpu frequently which pushes the load of our server between 5 and 10. I've been trying to troubleshoot the issue for ages - the qmail queue only has 28 messages in it (a few undeliverable ones that are stagnant).. I've tried reinstalling Qmail using the Plesk Autoinstaller but still have no luck. A google search only brought up qmail issues with the qmail-imap commands and nothing on the qmail-queue using high cpu. Sometimes 5 of them will be all using 100% cpu and it'll take around 3 minutes to navigate between pages on Plesk.

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
13626 qmailq 25 0 6244 1708 1264 R 99.5 0.0 0:25.23 qmail-queue
13805 qmailq 19 0 6292 2144 1620 S 82.2 0.1 0:03.83 qmail-queue


Cheers
 
Have you tried to rebuild MTA settings with mchk --with-spam or rebuild mail handlers?
