Without further information it's unlikely anyone can guess what the answer is.

Error does suggest code issue. It might be certain scenario or UI design triggers the issue. Share related code snippet to get more comments.

from above information it seems that there is a problem in your code. there can be no. of reasons for this.
you may be incrementing the index in such a way that some times it terminates without executing at last index hence doesn't gives error on the other hand sometimes its get executed, therefor giving error.
I suppose you should check your code first.

In this kind of problems use breakpoints it'll help you alot to solve your problems,or print the intermediate results to catch where you are getting wrong way

thanks
