CAUSE
This problem occurs because of a problem in the Rtcspl.exe process.

The Rtcspl.exe process is a managed application that calls the WaitHandle.WaitAny method of the Microsoft .NET Framework. The WaitHandle.WaitAny method uses an infinite timeout value. However, this method incorrectly passes a timeout value of 0x7FFFFFFF to the NTDLL function NTWaitForMultipleObjects. The value 0x7FFFFFFF corresponds to about 28 days. The correct value for an infinite timeout is -1.

Because the WaitHandle.WaitAny method passes a value of 0x7FFFFFFF to NTWaitForMultipleObjects, the WaitAny method incorrectly returns a value of 0 (zero). The Rtcspl.exe process interprets this returned zero value to mean that the Rtcsrv.exe process is quitting. Therefore, the Rtcspl.exe process also quits.

When this behavior occurs, the Rtcsrv.exe process is still running. When the Rtcsrv.exe process detects that the Rtcspl.exe process has quit, the Rtcsrv.exe process restarts the Rtcspl.exe process. After the Rtcsrv.exe process has restarted the Rtcspl.exe process 10 times, the Rtcsrv.exe process determines that a problem exists in the Rtcspl.exe process. Therefore, the Rtcsrv.exe process quits.
