Abrar, this error usually occures when your application is having an infinte loop. Please debug your CreateCopy() function and see if there is any false condtion to break the loop?

Thanks for reply

where should I found that method(CreateCopy()) I've no Idea I think its a predefined method.

Where abouts in your code does the crash occur? If you can narrow down what code is running when it happens that will help.

hello!
this error occurred when your memory or RAM is full,so i think in your application you retrieve data from database,so if it's the case,your data is so huge that your memory can't handle,so you must for example retrieve a little number of rows from the database.
provide us any more details for helping you better.
Regards!

Thanks alot for replying.
Yes we are retrieving huge data almost on every page but our server memory is 4gb RAM so I think its enough.But this error comes once in a while and the site gets down.I'm working on the sufyan2011 solution hope it fix the error and please help me in the easiest way to fix this problem as soon as possible.
Thanks & Regards
