NvRunCmd Terminates if SNA Application Internal Trace Is Enabled (229636)

SYMPTOMS

The NvRunCmd service may terminate unexpectedly when SNA Application internal tracing is enabled. Control Panel Services shows the NvRunCmd service with the status as "Stopped."

CAUSE

NvRunCmd writes a trace line after a particular function call, but before the corresponding GetLastError() function call. Therefore, the value returned by this function call is incorrect and causes the NvRunCmd to terminate. As a result, the NvRunCmd Service receives a shutdown request and the service is stopped.
