Oracle Fusion Middleware: Coreapplication_OBICCS1 Stop Error - OBICCS Hatası

Yesterday we managed to solve a problem which was very interesting. We werent able to login to OBIEE even though we were seeing the login page. We also havent changed out passwords during the time. Even though everything seemed to be correct, we couldnt log in to the system.

We ran opmnctl status and saw that OBICCS was kept from running. Something was preventing us from accessing to the bi_server

Solution: 
We executed " tasklist | findstr "pid" " to find which process was stopping us. We saw that a process called vmtoolsd.exe was running the same pid that our coreapplication_obiccs1 tried to use.

We killed the process by " taskkill /pid "pid_no" /F   " /F means force. We forcefully killed the process and then stopped and started the opmn. In the end we were able login to the system.
The original solution can be seen at Reference-2
