I have a NW65SP8 and GW8 HP2 System
and since a few weeks I expierence,
that if there are 10 or more IMAP
Sessions active the utilization goes
up to 100% resulting in unanswered
IMAP requests and sometimes even the
hardware makes an autoreboot as the
system is totally blocked.

If I stop IMAP on the gwia the utilization
goes down to almost idle. I am clueless.
