Hi All, I wonder if anyone can help me.

We have a Kerio mail server 7.4.3 build 7813, hosted from a 10GB RAM 2X2.8 Ghz Quad-Core Intel Mac Pro, most of the time there are no issues with the mail servers performance, however we have noticed recently that every wednesday at around 14:00 the mail servers CPU Maxes out.

There are no background activities going on, no backups and no updates. Nothing else is hosted from this server, it is solely a mail server so we can rule out this kind of thing. (hopefully)

Looking at the processes now, there is still 2GB spare of RAM, however the process "MailServer" is eating up over 700% of the CPU, everything else is still at around 10% or less.

Ive gone through the logs as much as I can without finding anything glaringly obvious, if anyone has any ideas why this spike my keep happening I would love to hear from you. All ideas are welcome

Many thanks,
