I've been using QTP for Webtesting with a DESCRIPTIVE PROGRAMMING approach.

I've been facing the following problem while running my scripts:

A JavaScript Error message dialog pops-up stating - "The Callee [server (not server application)] is not available". This happens only when I execute a particular script for a few iterations (I'm not sure how many iterations does it take, but on an average it takes 3-4 ierations.).

Has anyone of you encountered a similar problem while performing WebTesting using QTP?

It would be a great help if somebody can enlighten me on the probable cause behind this error and also a remedy for troubleshooting the same.

Thanks in adavnce.
