What Caused the Crash



  • Twice now my Pfsense 2.4.3 crashed, once yesterday and this morning…syslog doesn't seems to be aware either!

    Maybe try switching off 1:2200094 and see if the issues go away.

    Thank you NogBadTheBad for responding…I switched off both 1:2200094 and 1:2200007 which were ICMP and IGMP as I was getting a lot (my neighbor and I share the Internet and those are their nosy devices). The reason for the crash is still unknown though.

    It's very interesting that you posted a link to problems with Netmap despite I am running legacy mode as I would like inline mode. Learned today that lines such as this (Jan 21 20:33:58  kernel      438.215029 [1162] netmap_grab_packets bad pkt at 536 len 2331) that Suricata seems to be transmitting a packet (2331 bytes) to the "Host TX ring" which default size is 1500 bytes so it gets dropped.



  • I finally found out what was causing the crash…seems my motherboard was dying, and today it went belly up!
