zmstat crashes after upgrade to 6.0.1

[frankske]

Hi,

one of the Zimbra's I manage is a 6.0.1_GA_1816.UBUNTU6 Network Edition that was upgraded from 5.x. We upgraded about 2 weeks ago, and I've had four alerts from my monitoring systems that one of zmstat's processes (zmstat-cpu) stops working.

They all occur around 6:30 AM, which is (if I not mistaken) the time at which some cron/logrotate jobs should run.

Anyone else seing this? Is it a know bug/issue?

Are you seeing any errors in your log files /opt/zimbra/log/mailbox.log or /var/log/zimbra-stats.log?

(Also you might want to update your forum profile if you have upgraded to 6.0.x)

No errors what so ever. Still occurs from time to time, exactly at the time of the normal Ubuntu logrotate and daily system-cron. I suspect it's one of the processes that doesn't like the fact that it's logfile has changed?

That box is still on 6.0.1 NE, I'll try to upgrade to 6.0.2 this weekend.

Looks like 6:25 is when the daily crontab entries run, including logrotate.
The only one that I see that might be causing the issue is /var/log/zimbra-stats.log. The relevant logrotate config on my system is:

/var/log/zimbra-stats.log {
    daily
    missingok
    notifempty
    create 0644 zimbra zimbra
    postrotate
      killall -HUP syslogd 2> /dev/null || true
      su - zimbra -c "/opt/zimbra/bin/zmlogswatchctl restart" > /dev/null 2>&1 || true
    endscript
    rotate 0
}

Does yours look any different?

There are a few that seem logwatch related:

/var/log/zimbra.log {
daily
missingok
notifempty
create 0644 zimbra zimbra
postrotate
killall -HUP syslogd 2> /dev/null || true
su - zimbra -c "/opt/zimbra/bin/zmswatchctl restart" > /dev/null 2>&1 || true
endscript
compress
}

/var/log/zimbra-stats.log {
daily
missingok
notifempty
create 0644 zimbra zimbra
postrotate
killall -HUP syslogd 2> /dev/null || true
su - zimbra -c "/opt/zimbra/bin/zmlogswatchctl restart" > /dev/null 2>&1 || true
endscript
rotate 0
}

/opt/zimbra/log/zmlogswatch.out {
daily
missingok
copytruncate
notifempty
create 0740 zimbra zimbra
postrotate
su - zimbra -c "/opt/zimbra/bin/zmlogswatchctl stop"
su - zimbra -c "/opt/zimbra/bin/zmlogswatchctl start"
endscript
rotate 5
compress
}
