I don't believe this is in 9.1-RELEASE, so you > should test a stable/9 or 8.4-RELEASE (which is newer than 9.1-RELEASE) > kernel. I was one of the victims of this bug, a while back. Patched and ran a lot of diffs from avg@, even tried some stuff he wrote for -Current, but we got things working. And in the end it was integrated into -STABLE. So I'm running an unpatched -STABLE, and I did not have the problem since. Currently running: 9.1-STABLE FreeBSD 9.1-STABLE #172 r250288: Mon May 6 06:49:36 CEST 2013 And the system got rebooted only just this week for some maintenance. So either you take a look at the -Current code to see if more changes have been made, or perhaps ask avg@ for suggestions. --WjW
