Memory leaks in Version 7.5.1.1780 crashing w3wp process every couple of hours. CachedGroup or Castle Issues?

I read through this thread

http://community.sagecrmsolutions.com/t5/Developer-Web-Discussions/SLX-754-Out-of-memory-Exception/m...

And we're going to try getting more application pools setup but I compared some heap dumps and with perfview found the following things to be leaky and was curious if this rang any bells with anyone???

Here's a screen shot from perfview

Basically I took a heap dump and then two hours later another heap dump when the process crashed with an out of memory exception. What you're seeing in the screen shot is the diff of those two dumps.

Is this just all a product of the Session being InProc for the web client? So the SLX cache + the NHibernate Level 2 and LEvel 1 cache's
