ZCS 6.0.1 - Ubuntu 8.04

I had it happen last week. I stopped zimbra, but that process did not terminate, and I had to manually kill it. Then I restarted.

I ALWAYS see java running like crazy on the servers I've built!

I thought it was "normal"....?

We've got exactly the same since 6.0

5 was not exactly gentle on CPU but 6 on identical hardware (well identical other than we've given it more memory, another 2 cpus etc.) is 100% constantly.

Hi ,

I am not sure about this but below are few commands which I ran on my server and everything backs to normal you can try thi on your risk.

su - zimbra
logmysql.server stop
rm -rf /opt/zimbra/logger/db/data/*
chown zimbra:zimbra /opt/zimbra/db/data
chmod 775 /opt/zimbra/db/data
cd /opt/zimbra/libexec
./zmloggerinit
./zmfixperms --verbose --extended
su - zimbra
zmlogswatchctl start

We have the same problem with zcs-5.0.16.
Solved after upgrading to 5.0.19.

We have the same problem and it started last night. Cpu has been going on 97-98% for 13 hours now. Running Ubuntu 8.04. Need a fix for this asap! Is the commands that abhiz suggested safe to run in a production enviroment?

zmcontrol -v
Release 6.0.0_GA_1802.UBUNTU8 UBUNTU8 NETWORK edition.
