Test Stand Shut Down with no reason

Question

Hello ,
I'm using Test Stand 4.2 & LabWindows CVI 9.0 .
I'v created a program that checks 30 cards in Batch mode , using Test Stand as master that calls CVI functions from dll files i'v created .
In the program there are no error nor warnings But i have a strange problem for every 50 runs of the program I'm facing 1 Complete shut down of TS with no reason or warning .
TS simply shut down and not showing any message . This problem is very disturbing considering that full check for 30 cards using TS is Approximately 3.5 hours .
The shut down can occur at any part of the run with no repeated pattern , It can happen after 3 min or after 3 hours And by doing so the user need to restart the entire test from the start because TS 
didn't produced any Report .
I'm not denying that the crash can be in the dll files written in CVI but thats in low possibility .
I'm under Win Xp and using intel core2duo L7400 and 4 MB of RAM . 
Is there any option to avoid this problem ??
Thank You , Kobi .
