Vuser Struck at GExit mode and not getting stopped

Need Expert Advice.

I am running a load test using HP PC 12.60 version. I see a strange issue where the the VUSERs are gettig stuck at GExit mode. The results looks fine but the few vusers never stops. i have to manually cancle the run to bring it down to zero vuser. I checked all the settings and looks perfectly fine. Strangly this is happening mostly for SAP GUI client.

To troublshoot, i manually monitored the Load Generator and saw that the applications are opening, doing it iterations and closing it well, but same cannot be seen on HP PC side.

LR verion - 12.60, HP PC version - 12.60.

Any resolution would be greatly appreciated.
