repetitive status request: something to worry about?

[glenndm]

Hello
Today I wandered into the /var/log directory, for no specific reason as zimbra is running smoothly.
There I found mail.log and mail.info files reporting what seems to be repetitive status requests by (or from?) zmmailboxdmgr
They follow each other seconds apart and it seems to be going on for a long time.
