https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D252553 Bug ID: 252553 Summary: Kernel panic on big network and IO load Product: Base System Version: 12.2-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: dmilith@me.com Hello. I struggle with very annoying KP one of my dedicated servers. Long story short - it's i7 8 cores, 64GiBs RAM machine with ELK server (Elasticsearch 5.6 + Kibana 5.6 + Logstash 5.6), which gathers application = logs from our 350+ external hosts Let's say - it's under heavy network and IO load. I'm also using ZFS on root with sync=3Ddisabled on datasets (this way after a panic we lose only some = part of logs and whole ES index doesn't get corrupted). System has 64G swap on ZFS enabled, but it never gets really filled. Every 5-6 hours, (sometimes 5-6 days=E2=80=A6) kernel just panics there. Yesterday I build new, fresh 12.2 kernel with NETDUMP feature enabled, and = did setup of netdumpd on our second dedicated machine. In effect, I woke up and have some information from minidump with some info what's causing the panic (hopefully): https://gist.github.com/dmilith/9606ebf422ae1770b42d9e23f1116c7b --=20 You are receiving this mail because: You are the assignee for the bug.=
