Both Systems are OpenBSD 7.2 running on Dell PowerEdge R740

Is anyone able to interpret the stack trace?

today two of our firewalls crashed. after i was able to bring the first firewall back online, this one crashed again within a few minutes. this time i was able to take a stack-trace from the console: trap type 6 code 0 rip ffffffff81c38d68 cs 8 rflags 10246 cr2 0 cpl 0 rsp ffff80002b853590 ip6_input_if(ffff80002b853a08,ffff80002b853a14,29,0,ffff800002eed000) at ip6_input_if+0x1ae
