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.
