[SOLVED] Again high CPU

Postby Tripple » Mon Aug 29, 2011 2:58 pm

On my CentOS 5.6 32-bit 7.1.2 FOSS edition, for no reason, I start getting mails about high load avarage.
Looking at my server, top sais:

10477 zimbra 18 0 1393m 1.2g 11m S 197.5 30.0 172:19.96 java
Java: 197.5%
Is this the old bug that came back? How can I fix this?

We are tracking a couple issues for 7.1.3 that maybe causing this issue.
Bug 63467 and Bug 63621

would those bugs affect 6.1.14 as well? after upgrading to that this weekend 2 of my mailbox servers go from normal to 100% cpu. restarting seems to fix them for a day or so.

I had a problem where an n900 client using mail for exchange triggered a bug like this.

I've been experiencing the same problem on zcs-6.0.14_GA_2928_RHEL5_64 since I've upgraded from 6.0.13. Seems to be related to mailbox service on my server. The next time it happens I'll snag a ps output of the process and post it here.

zimbraServiceEnabled: antispam

zimbraServiceEnabled: logger

zimbraServiceEnabled: mailbox

zimbraServiceEnabled: mta

zimbraServiceEnabled: stats

zimbraServiceEnabled: snmp

zimbraServiceEnabled: ldap

zimbraServiceEnabled: spell


I only have top output of the process from today's event. 8G of ram on this server btw.

7087 zimbra 18 0 4152m 2.4g 10m S 198.7 30.7 283:02.41 java
After a zmcontrol mailbox stop && zmcontrol mailbox start, load is around 0.5.

It happened again faster than expected. I captured the ps output this time.

Again, a zmcontrol stop start was needed to bring back to life.

No. The only patch for 6.0.14 that I can find is a French patch of some sort. I did not see a 6.0.14 patch in announcements. Did I miss something? Am I looking in the wrong place?

Probably. You'll find it on the ZCS downloads page.
