You need to break you network into several areas and not send any of the
areas other than the one it is in to the PM3. I had the same problem with
50 PM3's and 20 Ciscos all in area 0, now running 7 areas and all is
smooth as silk.

I have many more routes flying around in OSPF, and if you have like an IRX
or Cisco directing traffic, you can easily filter what goes where.
