Few days ago I noticed that I can't login into zimbra, it seemed that the ldap died. So I killed the daemon and thought the problem is gone. But yesterday some users said that the server has a really bad performance, I decided to shut down the (virtual) server but then the whole system crashed.
After a reboot I did a fsck where some lost inodes where found. I started the zimbra server and everything seemed ok. But then I saw that the tomcat java process uses a lot of cpu (between 20%-80%). I thought maybe the server is doing some work for initalization but over night a had a really bad load (with no user access):
Here is the current load of the java process:
load average: 3.38, 3.73, 3.91
Has anybody an idea why I have such a bad performance?
