Hi,
Today a member of my 2 machines firewall cluster running 5.2 panicked
with following info (screenshot at http://tinypic.com/r/11t7nrl/6):
panic: pmap_remove_ptes: unmanaged page marked PG_PVLIST, va =
0x3c005000, pa = 0xfffff000
The machine, along with its identical twin, runs a standard suite of:
PF (including carp and pfsync), relayd and bgpd.
It is the 5th panic since the cluster was commisioned over a week ago,
all of them happened in the same function pmap_remove_ptes.
I found an older thread with Stuart reporting similar issue here
http://marc.info/?l=openbsd-tech&m=132593610913252
Could I ask for suggestions how to approach this and what might be a
root cause of the problem?
we hit the same crash on two different VMs:
Dec 20 11:04:40 mx01 /bsd: panic: pmap_remove_ptes: unmanaged page
marked PG_PVLIST, va = 0x3c000000, pa = 0x7aada000

From the last I have a crash dump and can provide further information
if someone want to take a look.
