 * Microsoft Windows Services for UNIX 3.5

SYMPTOMS
In Microsoft Windows Services for UNIX 3.5, you try to stop a Portable Operating System Interface (POSIX)-based application that is running as a Windows service. When you do this, the PSXRUN process may not stop. Additionally, the PSXRUN process may continue to show the STOPPING status.

This problem occurs when the following conditions are true:
 * You use the PSXRUN process to start the POSIX-based application as a Windows service.
 * You run the PSXRUN process on a multiprocessor-based computer.



CAUSE
This problem occurs because there are two threads in the PSXRUN process that call the SetServiceStatus function, and the two threads are not synchronized. One of the threads should always call the SetServiceStatus function before the second thread calls the SetServiceStatus function.
