Application error on Server 2003 standard

[Gipson]

I build an application in C# that does both serial and TCP/IP communications.
The application also uses some dlls build in VB.NET which are loaded using
late binding. I use the 'Trasport' package from ComponentScience.net for my
serial communications. The app runs in Server 2003 standard edition. I have
installed 8 serial ports to the server. My problem is, the application works
well on some server but crashes on others. On one of the servers, the app
crashes/dies completely without any pop-up and puts the following message in
the eventlog:
Faulting application ProcessorDriver.exe, version 1.0.1777.18426, faulting
module kernel32.dll, version 5.2.3790.0, fault address 0x000249d3.
I use create and destroy threads as much as I can and sychronize access to
the serial ports.
Can anyone help here.

Thank you,
Gipson.
