Please suggest me what could be wrong. Anyways..targeting ..maxdsiz,maxdsiz_64bit,maxtsiz,maxtsiz_64bit, maxssiz and maxssiz_64bit has not resolved the issue.

The most likely explanation is bad code. For example, free()'ing a chunk of memory that was not dynamically allocated. Is this an application that was developed in house?

Yep stephenson,its a inhouse product.

Seems to be working when increased maxdsiz. but still crossing the finger.

Trying to do all a sys admin can do for
this situation, waiting for developers response.

;)

Thanx Stephenson for ur time. Still leaving the tread open, in case it recurs ;)
