Strange exception after windows service shuts down

[cgambino]

Hello all,

I have a Microsoft VB.NET 2.0 windows service that throws a strange error a
few seconds after the service logs the "Service stopped successfully"
message. I was wondering if anyone could offer tips as to how I could go
about debugging this.

This is a multi-threaded windows service. I've checked things like open
file handles, and they are all closed before the threads stop. I've also
installed the service on multiple machines. The only thing that differs is P3
& P6 in the error message below. Strangely enough, P9 is the same on 2
different machines (a windows XP box and a win2k3 server).

Below is the error message from the Windows XP machine:
Event Type: Error

Thanks for any guidance you can offer
