In-fact I had this problem on a vanilla 6.0.4 install; I did compound things though as I had moved SSH onto a non-standard port due to internal security policies. The resolution was re-creating the SSH key and updating; restarting ZCS and then as root running
Code:
/opt/zimbra/bin/zmsyslogsetup
. Once that was done switch to the zimbra user and execute
Code:
/opt/zimbra/libexec/zmstatuslog
and check that /var/log/zimbra.log was being updated
Code:
grep "STATUS" /var/log/zimbra-stats.log | grep stats | head -n10
