IMAP memory and CPU

The IMAP task on 2 8.5.1 Domino servers I manage keep sucking up memory and CPU utilization until the servers are pretty much useless. I can’t tell what IMAP is doing that is utilizing all the resources. Anyone else seeing IMAP grow out of control? Any way to tune/limit that?

Which are your system spec? IMAP users? Which is the memory and virtual memory for the IMAP process?

I had a problem with IMAP in 8.0.2 having a memory leak. It pretty much sucked all the CPU but since we were migrating to another OS and that fixed that too.
