https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264257 Chad Smith <clearscreen@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |clearscreen@gmail.com --- Comment #79 from Chad Smith <clearscreen@gmail.com> --- Hello all, On the few servers we're running 13.1 we see these trap 12 errors too. The = most interesting bit I can contribute is we only see it on servers utilizing if_bridge.=20 My guess is the servers using if_bridge are seeing a lot more traffic across the wire and are therefore more likely to experience the packet sequence required to cause the trap 12 errors. When we rank servers by trap 12 error occurrence we see a correlation with bandwidth utilization (more bandwidth utilization, greater trap 12 error frequency). Happy to help in any way I can. --=20 You are receiving this mail because: You are on the CC list for the bug. You are the assignee for the bug.=
