threads exit without warning

I have an application that starts up a thread to watch for incoming tcpip. I
have run this over night and it suddenly just exits after a few hours. Any
ideas about what would make the thread exit?

The main loop looks like:

While True
..tcpip code

End While

The thread is fired up by a class I created, the thread is declared in the
class. The way it stops is in the finalize method of the class. There are no
other calls to end the thread in the program. The class is declared public
in a module.

Sub MAin looks like this:
Sub Main(ByVal args() As String)
Startup()''this fires up the thread
Application.Run(g_frmMain)''I use this form right now to shutdown and
diagnostics
g_frmMain.Show()
End Sub

Hi Jim,

Have you tried adding try/catch in the TCP/IP worker thread? If an
unhandled exception is thrown in that thread, the thread will be aborted.

I apologize for this post, I have found the 'End' statement that existed
when I ported from windows form application to service.
