Abnormal Exit

[Sun]

Hi

I developed some application with VS-C# on Framework1.1
My app included network, serial communication, ado, GDI+, etc..
and I used many Dll calls.

My develop machine is Windows XP home(2004 ver) , serivce pack 2 upgraded.
When my app run on my machine, It had no problem and non-stop run during 10
days.
but when it run on another machine( Win XP (2002 ver), sp1, Framework1.1),
my app was abnormal exit, no warning message, it just run during about 4
hours.
and the result was same at another machine( Win XP (2001 ver), sp1,
Framework1.1).

So, I searched event log, There is fault log
"Stopped Application xxx.exe, stop module hungapp, version 0.0.0.0, stopped
address 0x00000000."

Whoever has solution or experience. Please teach me
