Why am I getting errors after using the kill command to stop FCC processes?

Siemens Digital Industries Software does not recommend using the operating system kill command or the Windows Task Manager to stop an FCC unless safer methods have failed. Doing so can cause issues with the FMS fast cache, the FCC cache lock, and active FCC transactions. For recommended methods of stopping an FCC, see Shutting down a TCCS/FCC instance. If you use one of these methods to stop an FCC and receive errors, you must reset the user’s FCC environment.
