I'm having a painful time with a BM 3.9 sp2, NW6.5 8 server. Moving to a new ISP, I changed the public IP address. Everything is going well except that CPU utilization shoots up to 100% when filters are on. This is a change of IP, and the filters worked fine before.. I'm sorta at a loss on how to resolve this one. I've removed any logging from filters. I've also removed filter exceptions that were used to allow traffic to an from a GroupWise server. Any ideas?
