Kernel page fault on -current using carp and pfsync



Hi folks,
In the last few days we've experienced crashes of our
openbsd boxes, sometimes 2 or 3 crashes daily.
Trace output follows:
memset(d0581fc0,42,d5f3b56c,d5f3b544,afe,1242,0,a000001,14,0,0,0,1,0,0,4215a558)

Bad frame pointer: 0xd06a7e74
We've disabled pfsync this morning and the boxes
haven't crashed since. We've run the boxes in the past
without pfsync active and we haven't experienced any
crashes.
If we can do something more to help debug this issue
please let us know.
The boxes are running GENERIC as in the 16.02
snapshot.
