error stop a Windows service

Question

Hello everyone,

Here is my OnStop method of Windows service application. When click stop, the error message is, "Error: 1067 The process terminated unexpectedly".

I have tested if remove the Join method, the service can stop gracefully. Does it mean Join method is not allowed to be called in OnStop method of a Windows service? Any ideas?

[Code]
protected override void OnStop()
{
    MyWorkerThread.Join();
    this.ExitCode = 0;
}
[/Code]

thanks in advance,
George
