AMS crashes when stopping the service

When I stop the AMS service, it crashes the application and generate errors in Windows Error Reporting.

Faulting application name: ams.exe, version: 1.40.0.0, time stamp: 0x5c4798f9
Faulting module name: reversesnmp.dll_unloaded, version: 1.40.0.0, time stamp: 0x5c47984c
Exception code: 0xc0000005
Fault offset: 0x00000000000019e9
Faulting process id: 0xca0
Faulting application start time: 0x01d4eb0e1030583f
Faulting application path: C:\Program Files\OEM\AMS\service\ams.exe
Faulting module path: reversesnmp.dll
Report Id: ecde7995-0eb1-4a8e-ab8f-6ebd05e86da5
Faulting package full name:
Faulting package-relative application ID:

Is there a proper way to stop the service without generating crash events?  Is there some other service I should be stopping first.  Should I KILL the process intead of stopping the service?

Thanks
