zimbra.log empty after rotate

[shrek]

I just setup a new Zimbra server on Ubuntu Server 10.04 LTS. All seems well but I noticed today when I tried to trace some email delivery issues that my zimbra.log is empty since this morning. Yesterday it worked fine.

I've tried to restart the server (multiple times) but didn't do anything...


-rw-r--r-- 1 zimbra zimbra 0 Oct 8 06:44 zimbra.log
-rw-r--r-- 1 syslog adm 286960 Oct 8 06:44 zimbra.log.1.gz

I looks like it's going bad after the logrotate but I don't understand why.

Any ideas what could be going wrong here?

Thanks!

Restarting rsyslog worked for me:

-rw-r--r-- 1 syslog adm 91K 2010-10-10 16:58 zimbra.log

It changes the permissions, you probably have zimbra:zimbra at the moment, but the above is what you end up with afterwards. Im not sure what knock on affect this has, ie if zimbra can still do what it needs to the file, but i guess we'll see.

Cheers,

The mine stopped as well:

ls -al zimbra.log*
-rw-r--r-- 1 zimbra zimbra 4199 Oct 22 12:10 zimbra.log
-rw-r--r-- 1 zimbra zimbra 53868 Oct 18 04:25 zimbra.log.1.gz
-rw-r--r-- 1 zimbra zimbra 68725 Oct 15 04:25 zimbra.log.2.gz
-rw-r--r-- 1 zimbra zimbra 38329 Oct 12 04:25 zimbra.log.3.gz
-rw-r--r-- 1 zimbra zimbra 61631 Oct 11 04:25 zimbra.log.4.gz

I even see a service what should be writing to it:

zimbra 5800 1 0 11:39 pts/1 00:00:00 /usr/bin/perl /opt/zimbra/libexec/swatch --config-file=/opt/zimbra/conf/swatchrc --use-cpan-file-tail --script-dir=/opt/zimbra/data/tmp -t /var/log/zimbra.log


Why does it stopped, can anyone help me out with this problem?

Ok as you can see i did a list after a /etc/init.d/syslog restart

And since 10 minutes zimbra.log is growing again.

Hmm it looks like a bug of zimbra?

Same problem on my Ubuntu 10.04 LTS ith ZCS open-src v.6.0.8... and a solution :

Hours after after a logrotate (daily), the 2 zimbra .log files are still empty in /var/log/ :
-rw-r--r-- 1 zimbra zimbra 0 2010-10-28 06:45 zimbra.log
-rw-r--r-- 1 syslog adm 39112 2010-10-28 06:45 zimbra.log.1.gz
-rw-r--r-- 1 syslog adm 112072 2010-10-27 06:38 zimbra.log.2.gz
-rw-r--r-- 1 zimbra zimbra 0 2010-10-28 06:45 zimbra-stats.log

And on the zimbra web amin console, no recent data for services status, and when trying to displays graphs I get a popup error :
"Mail : system failure: Unable to read logger stats Code d'erreur : service.FAILURE Method: GetLoggerStatsRequest Détails :soap:Receiver"

Only 2 solutions works for me :
- full reboot of the Ubuntu
or
- changing owner/group of the two .log files to syslog:adm (instead of zimbra:zimbra) : after a few minutes all is back ok, all log files growing and web console grpahs/status working ok :
chown syslog:adm /var/log/zimbra.log /var/log/zimbra-stats.log

Wondering if I should put my "chown" in a crontab,
or should I try modifying own/grp in /etc/logrotate.d/zimbra ?

I created a bug report on :
