I think in my case are more than one problem:
Errors about mysql are in zmstat.out from time to time (once or twice in a month?). So i think this is not a problem, maybe it relate to restarts of zimbra.

Errors like
Code:
Warning: Not possible to monitor process stats
..and..
Code:
04/12/2008 07:30:00: ERROR: No such process: '30196'
..are in my zmstat.out since i have zimbra on server. So I think this is also not related to problem with graphs.
I don't have another errors in zmstat.out. I don't have any errors in syslog related to stats. I don't know why stats not working and where to find why.
