What happens if you set one of these sysctl values to 0? (This disables
SMP changes from 5.4 to 6.0.)
debug.mpsafevfs: 1
debug.mpsafenet: 1
debug.mpsafevm: 1
Thanks for the suggestion!
I just did so and rebooted both machines, so we'll see.
I remember unseting debug.mpsafenet before 5.4 due to some ipfw
limitations, but didn't know about the other two.
And is there a possibility (performance-wise) to build a kernel with
WITNESS and/or INVARIANTS options compiled in. This will give more info
about possible locking problems. Your system will run slower. And
because of this the problem may not occur anymore, but it is worth the
try.
Both machines are not much loaded, so I could afford slowing them down a
bit for a while (I hope it won't be several times slower). I will do
that at some point later if the problem still persists.
I hope I won't be forced to downgrade to 5.4, though I'm already working
on that (just in case).
Regards,
Atanas
