I have a strange problem in one application.

This app run as service on Windows NT 4 and sometime it stop to run by itself!

The event was set and the only way to stop the program is to kill it from the task manager or stop the service manually from the service manager.

Here is a part of the code:

...
ON SHUTDOWN CLEAR EVENTS
READ EVENTS
ON SHUTDOWN
*code to log this event
...INSERT INTO Blabla...
CLOSE DATA ALL
...

When the program was stopped from both of the ways described the log was not made, but when it stop by itself the log is made!

My question is: What can clear the Read events or fire the On shutdown event?

Please help!!!
TIA :0)
