Daniel,
the system is still running without panic, but i found the following log
entries from last night:
May 24 23:28:57 charon kernel: pf_route: m0->m_len < sizeof(struct ip)
May 24 23:28:57 charon kernel: pf_route: m0->m_len < sizeof(struct ip)
Do you think that this may be related to the panics?
I've found this error message two times in contrib/pf/net/pf.c.
I can't say which of them or both have printed the message.
Kind regards
Joerg
