From 2 days i got very strange issue, i never had this before.
My local Zimbra server took 100 % of CPU from 2 days 24/7.
I even try fsck but it doesn't solve my problem.
First what i would like to show is output from nmon.
I can't see there process what take almost all cpu. CPU Utilization show usage by system at 92 %.
then i try with atop
but no answer.
Then i try with memory
I know 2,5 gb is to small, but should work.
And as you see, in swap 0 Mb - free 1,5 GB.
Then i show load:
It's very hight according, there is no "real load".
I attach syslog and messages. Myself i can't find there problem.
I really don't know what should i do.
2 days before, everything work great. I don't do any changes.
