System is restarted when starting a virtual machine

Hi,

Here is my Player version:

Recently, when starting any virtual machine, I got whole system (VMware's host) reboooted. Please help me!

I tested by restart VMware (/etc/init.d/vmware), backup and emtpy all log files:

/tmp/vmware-thepostman/vmware-player-xxx.log

/var/log/vmware/hostd.log

and try to start a virtual machine, but there isn't sigle new entry was recorded in those log files (checking after system booting up).

The same with message log file.

My system:

CentOS release 6.3 (Final) - Linux thepostman 2.6.32-279.22.1.el6.i686 #1 SMP Wed Feb 6 00:31:03 UTC 2013 i686 i686 i386 GNU/Linux

Hw: Proliant DL580 - G5.

All virtual machine located on internal hard disks.

Thanks,
