https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D271945 --- Comment #2 from Cy Schubert <cy@FreeBSD.org> --- I think the common thread here is poudriere-bulk is running. When running w= ith -j number of jobs the likelihood of this occurring is > 50%. Whereas with -= j 1 it will never happen. I have no zpools with errors. I have another machine, not quite configured the same (fewer disks), also running poudriere but in this case the poudriere jails are all i386 jails whereas the machine that panics, the poudriere jails are all amd64. I don't know if this has a bearing on this problem or not. My panic string is usually like this, though at times I will see a c++ proc= ess in a detected deadlock. Unread portion of the kernel message buffer: panic: deadlres_td_sleep_q: possible deadlock detected for 0xfffffe00c0d6d7= 40 (p ostgres), blocked for 180239 ticks cpuid =3D 0 time =3D 1689121195 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe00851b7= e00 vpanic() at vpanic+0x149/frame 0xfffffe00851b7e50 panic() at panic+0x43/frame 0xfffffe00851b7eb0 deadlkres() at deadlkres+0x32a/frame 0xfffffe00851b7ef0 fork_exit() at fork_exit+0x82/frame 0xfffffe00851b7f30 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe00851b7f30 --- trap 0, rip =3D 0, rsp =3D 0, rbp =3D 0 --- Uptime: 8h51m9s It's usually postgresql which is the DBMS for gitea. But, as intimated abov= e, sometimes it's a c++ that's listed as the "cause." --=20 You are receiving this mail because: You are the assignee for the bug.=
