It happened, again.

Yesterday, exactly at 19:15, my /var/log/zimbra.log rotate and since that the new zimbra.log is empty and I get Logger service must be installed in admin console.

zimbra@myserver:~> ls -lrt /var/log/zimbra*
-rw-r----- 1 zimbra root    54112 Mar 25 19:15 /var/log/zimbra.log.4.bz2
-rw-r----- 1 zimbra zimbra  44181 Mar 26 19:15 /var/log/zimbra.log.3.bz2
-rw-r----- 1 zimbra root    43452 Mar 27 19:15 /var/log/zimbra.log.2.bz2
-rw-r--r-- 1 zimbra zimbra      0 Mar 28 19:15 /var/log/zimbra.log
-rw-r----- 1 zimbra root   136127 Mar 28 19:15 /var/log/zimbra.log.1.bz2

Answering your answer, my timezone is CEST and I haven't installed tzupdate (is it useful?)

I tryed also:

logmysql zimbra_logger
mysql> select * from service_status;
Empty set (0.00 sec)

@D!
