If you search back far enough in this forum, you'll find at least a couple threads regarding the 3600 platform and high CPU with ASM. My 3600 which is rock solid with LTM, would core just downloading ASM attack signatures. I have no experience with version 11, but after going round a round with support for a couple weeks a support tech confided to me that it was a known issue and his words not mine "ASM should be running on it's own hardware". At that point I stopped trying. I've been an LTM admin for 6 years and it is rock solid. In my experience, add ASM on a 3600 and toss that reliability out the window. In frustration, I actually asked on the forum a couple years ago if anyone was running LTM+ASM reliably on a 3600. There wasn't a single response.

 

 

If you do get it stable, please update the thread. I'd love to finally get it implemented, but I'm not wasting anymore time on it until I know somebody else actually got it working.
