Getting error email from zimbra server for logger service

[djingo]

Hello all,
I'm getting in the admin email 3-4 mails from zimbra per day saying that the logger stopped but reporting always the same time "04:02:45"


Jul 19 04:02:45 mail zimbramon[8042]: 8042:err: Service status change: mail.combiline.it logger changed from running to stopped

When I connect to the server, zmcontrol status shows everything running.

I'm using Network edition 6.0.10 on Centos 5.4 64 bit

Kindly are there any suggestions why this is happening ?

Thank you!
Mark
