Java running on VMware

Hi

I wonder if you can assist in a issue I am experiencing. We are currently running a jvm with the following settings:
       Name:Java HotSpot(TM) 64-Bit Server VM
       Version:19.1-b02
       Vendor:Sun Microsystems Inc.
       Architecture:64 bit
       Info:mixed mode

We are running on the followinhg environment:
-      Windows 2008
-      Virtual Server with 12GB virtual memory and 4 virtual CPU’s
-      JVM is started as a windows service

Symptoms: An unexpected service shutdown occures, but does not look like a jvm crash.

Status of JVM at the time of failure:
 
 

Status of the server at time of failure:
 

Our logs don’t say anything about a shutdown or anything (went down between 13:35 and 13:37):
2011-08-11 13:35:36 CAT [ISP.0090.0003C] *********************************TASKID: 117555
2011-08-11 13:35:52 CAT [ISP.0090.0003C] *********************************TASKID: 117556
2011-08-11 13:37:32 CAT [ISS.0025.0001C] Integration Server 8.2.1.0 Build 315
2011-08-11 13:37:32 CAT [ISS.0025.0006I] License Manager started


Things I’m a little confused about:
-      I would have expected a constant memjory utilization on the box as we set min and max memory to 10G
-      Memory doesn’t look that high on the jvm.
-      There is no dump you’d expect if the jvm crashed



Any ideas are most welcome.
