Maybe some help out there?
My server gets unresponsive after a while (sometimes once per day, sometimes less). First I checked the hyper-visor (VMWare) and the host but it happens on other hosts and other storage too.
When the server is unresponsive, one core is at 100% (2 cores, 4 GB RAM) and the server is "dead". I can't even login to the console.
This happens a few weeks now, before the system was rock solid.
Last entry in syslog is always
"pmg-smtp-filter[12345]: end database maintainance (x ms)"
