https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213903 --- Comment #8 from Ben Woods <woodsb02@freebsd.org> --- (In reply to John Baldwin from comment #6) > In kgdb, can you go up to the frame that faulted (13) and print out 'ts' = and 'queue'? Apologies for the delay in replying, I had deleted this core, and moved poudriere to another box to avoid these crashes. I had to reinstall poudrie= re to recreate the high load on the server in order to reproduce this kernel crash. I have printed the values you requested below. Please let me know if you wo= uld like any more info. I'll keep the core handy this time :) # kgdb /usr/lib/debug/boot/kernel.GENERIC-NODEBUG-VIMAGE/kernel.debug /var/crash/vmcore.last GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
