Process Scheduler exhibits very high memory/processor utilization which leads abended processes.

We're in the process of opening an SR on this, but I figured that it might be helpful to get this out to the community.  We are getting ready to go live with Tools 8.51.11.  We are seeing bad behavior on the process scheduler servers.  We have 3 separate process schedulers, each running on a separate Windows 2008 server.  What we are experiencing is that when we start to see a heavy load on a single process scheduler, say 10-15 processes simultaneously, the CPU and Memory utilization go up to 98-100% each.  At ths point, many processes will start failing.  Sometimes,
