This is known and long-stanging problem in the FreeBSD network stack. It shows up when you have lots of network interfaced created/removed frequently like in your case of Network Access Server (PPtP, PPPoE etc). Generally, people run into this problem using mpd5 network daemon. mpd5 uses NETGRAPH kernel subsystem to process traffic and if an interface disappears (f.e., ,user disconnected) while kernel still processes traffic obtained from this interface, it panices. There were lots of reports of this problem. Noone seems to be working on it at the moment. You should fill a PR using Bugzilla and attach your logs to it. Eugene Grosbein
