EXCEPTION_ACCESS_VIOLATION in Microsoft IIS

[rochumenon]

I have an web application written in C++ deployed on Microsoft IIS 6.0. As part of request processing, it connects to oracle database. However recently every 7-8 days, the below error appears in our logs and the web service stops
processing further requests until I perform Microsoft IIS restart.

Can someone please help me resolve the issue?

perhaps if you showed us the code we could help a bit.

General thought is a dodgy pointer, but no one can help without the code.
