CF8 - cfimage rotate causing high CPU utilization

CF8.0.1 Cumulative hotfix 4, if I try to rotate an image with CFIMAGE or it's related functions, CPU utilization climbs to close to 100% then never drops below 50% again until I restart the service. It exhibits this behavior on two of my CF servers, my developer and my staging servers.

Here's the code:

<!--- make new image file in memory --->

<cfset myImage=ImageNew("",200,18)>

<!--- draw some text --->

<cfset ImageDrawText(myImage,i,3,15)>

<!--- rotate it note: either method below yields the high utilization--->

<!---<cfset ImageRotate(myImage, '90','bicubic')>--->

<cfimage action="rotate" angle="90"  source="#myImage#" name="myIMageRotated">

<!--- display the image in the browser --->

<cfimage source="#myIMageRotated#" action="writeToBrowser">

Any help would be appreciated
