I've built new SuperMicro server (same hardware platform with ECC memory, same
NanoBSD image
and configuration but no lagg interfaces and only one uplink em0 and another
downlink em1).
After 3 days 20 hours it paniced with new kind of panic.
Sadly, I forgot to enable crashdumps this time. Still, it had second panic
(Sleeping thread owns a non-sleepable lock) before reboot.
And it did not reboot itself, IPMI watchdog rebooted the box after 5 minutes.
My servers run quagga/ospfd too, hence igmp in stack trace:
