Windows server 2012 + Exchange Server 2013 Cumulative Update 2 (CU2-v2) = EventID41 Kernel-Power

May be somebody already got this problem and knows how to fix it.
After installing Cumulative Update 2 (CU2-v2) we have randomly rebooting system! 4 servers with the same problem.
This is the error mesage:

- <Event xmlns="">
- <System>
  <Provider Name="Microsoft-Windows-Kernel-Power" Guid="{331C3B3A-2005-44C2-AC5E-77220C37D6B4}" />
  <TimeCreated SystemTime="2013-10-01T07:27:03.218650400Z" />
  <Correlation />
  <Execution ProcessID="4" ThreadID="8" />
  <Security UserID="S-1-5-18" />
- <EventData>
  <Data Name="BugcheckCode">239</Data>
  <Data Name="BugcheckParameter1">0xfffffa8003d47980</Data>
  <Data Name="BugcheckParameter2">0x0</Data>
  <Data Name="BugcheckParameter3">0x0</Data>
  <Data Name="BugcheckParameter4">0x0</Data>
  <Data Name="SleepInProgress">0</Data>
  <Data Name="PowerButtonTimestamp">0</Data>
  <Data Name="BootAppStatus">0</Data>

It starts at the next day after update was installed.  

BTW this is vmware virtual machines so problems with power supply can be excluded...

Can you grab the dumpfiles from the VM to see whats going on with the OS?  I use whocrashed to review dumpfiles to hopefully get a better idea:

I would also (on one server) remove the update, if that resolves your issue then you can always put in a call to microsoft for assistance.  So far CU2 v2 has been hit or miss with some technicians.

looks like you are right! I disabled helth manager service and till now servers not rebooted..
I will wait for 2-3 more days and if everything will be OK i will start to read how to configure Managed Availability (i want to disable server reboot option). And will mark you answer as solution :)
