Dear All,

We're running ZCS 506 version on CentOS 4.4 and we found
the "stats" service sometimes will stop.

We've checked /var/log/ and /opt/zimbra/log/ and can't find
useful information why stats service is stopped.

Searching this forum, we found the /opt/zimbra/zmstat/zmstat.out
shows :

=================

Have anyone seen this before and happen to know how to fix it?

Thanks.
