Hey, I'm new here, so if this is on the wrong ng, please let me know.

We've been accessing nntp newsgroups through groupwise for some time now. In the past few weeks, we've noticed that accessing the ng's fails, until we unload ipflt and reinitialize the system. We recently upgraded to BM 3.8, as well as needing to upgrade several other parts of the system to allow the BM upgrade to happen. Anyone know where to start looking? I wasn't in on the upgrades, so I'm not sure in detail what may have changed, but some possibilities would be nice. Thanks!
