Could I convince you to enable "keepsyms=1" to the boot-args, so we get function names?

I got around this problem for a while by increasing the RAM allocated to zfs and by rebooting the system every day.

Just had another crash today and have uploaded the report below with the keepsyms boot option enabled:

_avl_rotation ? Hmm well, that's a new one. That code is pretty straight forward, so possibly suggesting the avl tree for dbufs are bad somehow.

Just had another kernel panic. It looks like it occurs somewhere else:

Code: Select all
panic(cpu 6 caller 0xffffff7f8ea63090): VERIFY3( rwlp->rw_pad == 0x012345678 ) failed (0 == 305419896)


Checking rw_pad against that number is the DEBUG (always on in rwlock) code checking that the rwlock has been initialised before use. The
number "305419896" is unknown, so it would appear to be random memory (and not the case where rwlock was in-use then
destroyed, as that has another clean number).

This implies the dnode_dest() code is destroying random memory, and not a real dnode. All triggered by a memory reap
due to memory pressure.

Which again is from eviction. It would suggest random memory changes, which is notoriously hard to track down.

FWIW I just saw my first KP in a very long time after upgrading to 1.9.2, on a 2010 Mac Pro running 10.13.6. It had a fair amount of uptime first though, at least a few weeks, so might be something random and unrelated. Unfortunately it's been long enough that I didn't still have any boot-args enabled (and had even forgotten SIP means you need to go to recovery to set them nowadays) but now have keepsyms=1 and debug=0x124, so if it comes up again maybe I can supply another data point.
