[SOLVED] ZCS 6.0 - zmlogger service using very high CPU

[rosenbj]

I have been running Zimbra for about 2 years now and have upgraded periodically throughout the 5.x code stream. I just upgraded Zimbra from 5.0.16 to "Release 6.0.0_GA_1802.RHEL5_64_20090830141723 FOSS edition" and have read about the changes to the zmlogger process.

My issue is that since the upgrade, the zmlogger process appears to be constantly using excessive CPU. Here is a typical output from the top command and this is pretty typical (going from 99% to 119% with each cycle):
Mem: 2051248k total, 1964088k used, 87160k free, 23248k buffers
Swap: 4095992k total, 0k used, 4095992k free, 630704k cached

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
6894 zimbra 25 0 54976 8772 2436 R 99.9 0.4 2:21.38 zmlogger

I have attached the output from the commands recommended by Zimbra from zmlogger troubleshooting section. Also, the /var/log/zimbra-stats.log file is growing extremely quickly and doesn't appear to be getting "logrotated".

As much as I like the new functionality, I think I may have pulled the trigger a little early upgrading from 5.0.16 to 6.0.

Thanks for any insight regarding this issue....

BUMP

Any ideas? I have gotten numerous Nagios emails about High Load. This morning my machine is practically nonresponsive and I will probably have to hard reboot.

Thanks,
Jeff

I was having the same problem. I found a post by Raj that did the trick for me

su - zimbra
zmlocalconfig -e zmmtaconfig_interval=6000
zmprov mcf zimbraLogRawLifetime 7d
zmprov mcf zimbraLogSummaryLifetime 30d
/opt/zimbra/libexec/zmlogprocess

su - zimbra
crontab -e
*/60 * * * * /opt/zimbra/libexec/zmstatuslog

You might also want to consider disabling any unnecessary services on your server (if they're not already disabled).

Thanks for the reply. I made the necessary changes. the zmlogger process still consumes a lot of CPU periodically but it does finally free up CPU resources when watching it under "top". My "sar" graphs now show a more normalized CPU usage across the 4 CPUs. It still does take significantly more CPU than my pre Zimbra 6.0 (5.0.16) CPU load graphs. My other services don't need to be disabled since the only server that really ever consumes CPU (other than Zimbra) is my Netapp simulator. Hopefully as Zimbra 6.x matures, the zmlogger process issues will be addressed.

Thanks again,
Jeff

PS - The /var/log/zimbra-stats.log appears to still be growing very fast. From 14:32 to 15:47 and the log is already just shy of 9MB.

Ok.

Beginning with 6.0, the architecture of the logger service has changed
This is as explained in release note & following wiki.So future releases should take care of this.
