I agree with brian, Exchange itself was just a unfortunate bystander of the memory leak issue, but since mailboxes are on the BACKEND Disk's via Storage groups, its Exchange exercising the disks, to read and write and it's the MPIO.sys being leaky that is causing stuff to go to hell in a handbasket.
Again, depending on usage it might take days or weeks, for the memory to leak back out, so we are evaluating with the new version of the MPIO.sys file and working from there. Brian is also correct, Poolmon will show if you have the issue and which driver is doing it, again I am no Poolmon expert, but from what I was showed, it all made sense.

We don't user Exchange and very few clustered systems, but almost everything is EMC attached using PowerPath, so this worries me.
