I had simlar problems, but much higher Averaged RPC Latency time (climbing), very little in the queues, disk performing fine.
Do you have any processes with unusually high cpu % Our problem turned out to be GFI Mail Security, getting stuck decompressing archive attachments and creating large files in the GFI proc folders. (several 4gb files). Either it was a problem decompressing, or GFI was not recognising mail bombs and decompressing them correctly. I found the MS Exchange Performance tuning document quite interesting.
