CPU High Spikes around every 2 minutes ZSC 7.1.4

[mrcoffee11]

Hi guys,

On my Fedora 11 x64 system I got this problem since my upgrade a few hours ago from version ZCS 7.0.0 to 7.1.4. Can't seem to find a solution for these hight CPU spikes.

I also have the same problem on a newly installed server running Centos 6.2 with 2GBs of RAM and a fresh install of ZCS 7.1.4 and zero mailboxes. Both are VM's are running on VMware vSphere5.

I edited the crontab adjusting jobs that run every 2 minutes to a longer time period.

Also entered these commands which worked for older versions:

 
zmlocalconfig -e zmmtaconfig_interval=6000
zmprov mcf zimbraLogRawLifetime 7d
zmprov mcf zimbraLogSummaryLifetime 30d

Still got these spikes every 2 minutes, sometimes 2:20 minutes. (see the graphs)

Any suggestions on what this is and how to increase the time interval?

Thnx,
Roderick

Bump. There must be a Zimbra developper or Zimbra-Super-Gourou who can answer this question?

[mrcoffee11]

Still can't find a solution/cause. Other people seem to have the same issue.
High Java CPU usage question

I uploaded another graph to show the difference in CPU usage before the upgrade from 7.0.0 and almost two weeks ago to 7.1.4.

Grtz,

maybe status log updating every 2min and consuming alot cpu %

try:

su – zimbra

crontab -e

*/60 * * * * /opt/zimbra/libexec/zmstatuslog

[mrcoffee11]

I already adjusted most of the crontab jobs directly after the upgrade, including this one. Thnx for trying. More sugestions welcome!
