We had a problem like that for a while when we started vision processing. Look for memory leaks, undeleted pointers to images, etc. some of the different ways of image acquisition don't overwrite the old image but put a new one in memory. Try a loop counter to see how many times it runs. if it runs 20-30 loops and then stops, that's most likely your problem.

Can you post your code that handles images?
