KB484960: Unable to stop or restart the Modeling service through Services after it crashes in Windows

Description 

After the Modeling service crashes, the

RUNNING_PID

file in

./ModelService

is not deleted, so Windows Services doesn't recognize that the Modeling service has stopped. Thus, you can no longer stop or restart the Modeling service from the Windows Services program. 
If you try to continue to call the Strategy Library APIs (either directly or via Strategy Workstation), you may get an error message stating that the Modeling service is not configured.

Why is this happening? 

The Modeling service crash depends on the machine's memory allocated to the Modeling service. For example, in a Windows machine with 16GB RAM, it takes about 120 open changesets in a few minutes to crash it. 
 

Workaround 

You can run

stop.bat

manually in command line (administrator mode) and then you should be able to refresh the correct status in Services and restart the Modeling service from Services again. The

stop.bat

file can be found in

./ModelService/bin

.
