i've migrated from 7.2.2 on ubuntu 8.04 32bit to 7.2.2 on ubuntu 10.04 64bit, and mails seems to be flowing. zmcontrol status shows all services running, but the web interface shows all services as failed!? also, no stats available. i think this has something to do with zimbramon not working correctly, but i'm not really sure how to troubleshoot. observations, output:

zimbra@box~$: zmcontrol -v
Release 7.2.2_GA_2852.UBUNTU10_64 UBUNTU10_64 FOSS edition.

zimbra@box~$:ls -l /var/log/zimbra*
-rw-r--r-- 1 zimbra zimbra 0 Feb 15 01:01 /var/log/zimbra-stats.log
-rw-r--r-- 1 zimbra zimbra 0 Jan 25 22:35 /var/log/zimbra.log

so i think this is probably key to status not being right - aren't those updated from these logs?
i've trolled the forums but everything i'm seeing is for older versions! from what i've read, the logger was re-written with v6, right?

point me in the right direction! meanwhile - off to research how the logger and logswatch work, maybe i can pick something up there
