Domain Controllers not creating crash dump files

-

hi everyone,

we running windows 2008 r2 domain controllers in forest level windows 2008 r2. have 70+ domain controllers. of virtual running on vmware. only the main data centers having exchange have physical domain controllers. infrastructure upgraded 1 windows 2003. 

from last 2 months many virtual domain controllers facing unexpected reboots. there no fixed dc or pattern. have configured kernel crash dump files generated crash dump files not getting generated on 1 of them.

the virtual domain controllers have 2.5 gb ram , page file 2.5 gb. if increase page file size issue same.

i used notmyfault.exe tool sysinternals check whether manual trigger generates dump file. surprise dump file created successfully. tried different option in notmyfault irp, deadlock etc , in occasions dump file generated successfully.

we need find reason why our domain controllers getting rebooted. much appreciated.

regards,
abhi
