sql-server-2008

We recently upgraded a database server from SQL 2005 to SQL 2008 64 bit. CPU utilization is oftentimes running at 100% on all four processors now (this never happended on the SQL 2005 server). When I run sp_lock I see a number of processes waiting on a resource called [ENCRYPTION_SCAN]. I am not using any SQL 2008 encryption features. Does anyone know why I would have tasks waiting on this resource? It appears that whenever I have four processes waiting on this resource, CPU hits 100% on all four processors.

So, I've got an app at work that encrypts a string using ColdFusion.
