Error "AX Attempted to read or write protected memory. This is often an indication that other memory is corrupt

Hi All,

I am getting this exception in eventvwr repeatedly.
We are running AX 2009 RU7,so do we need to install RU8 ?

The exception in eventvwr is as below:

Microsoft Dynamics AX Business Connector Session 35.

Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
