It was happening under 13.2-RELEASE-p10 so I upgraded to 14.0-RELEASE-p6. It still occurs. First the panic: Fatal double fault rip 0xffffffff82b45307 rsp 0xfffffe00037f7f10 rbp 0xfffffe00037f8140 rax 0 rdx 0 rbx 0xfffffe00037f8170 rcx 0 rsi 0xfffffe00037f8170 rdi 0x4b3cc420 r8 0 r9 0x700000000 r10 0xfffff80010457880 r11 0x4 r12 0xfffff8001089e800 r13 0x20000 r14 0 r15 0xfffffe00037f8174 rflags 0x10282 cs 0x20 ss 0 ds 0x3b es 0x3b fs 0x13 gs 0x1b fsbase 0x878b0a130 gsbase 0xffffffff82a10000 kgsbase 0 cpuid =3D 0; apic id =3D 00 panic: double fault cpuid =3D 0 time =3D 1713229261 KDB: stack backtrace: Uptime: 23d8h18m48s I'd love to share more about the crash, but savecore fails on boot: Apr 16 20:59:06 membrane kernel: Starting syslogd.

Apr 16 20:59:06 membrane kernel: Apr 16 20:59:06 membrane savecore[984]: /dev/vtbd0p2: Operation not permitted I can reproduce it at will by configuring bird2 to export the BGP IPv4 route table (960959 entries) to the OS (already exporting IPv6 route table withou= t an issue). Note that I do this on multiple other FreeBSD 13.2/14.0 hosts with= out a problem so it is something specific to this box's configuration. --=20 You are receiving this mail because: You are the assignee for the bug.=
