High DB Server CPU When Opening Form In Dynamics AX 2012

Hi,

I have an issue with Microsoft when a particular form is opening the CPU on my database server spikes. On the application the form takes ages to open(up to 40 minutes).

I ran a Profiler trace selecting the ShowplanXML, STMT Batch starting, STMT Batch Completed, SP Starting, SP Completed, SP STMT Starting, SP STMT Completed and nothing obvious appears.

Is there anything else I should check for?

Cheers

Paul
