Hi all,
we are running a backup firewall machine which regularly freezes since
OpenBSD 4.6. The configuration also changed at this time. When frozen no
input is accepted by serial or keyboard console. Breaking to ddb works
though. The output of ps and trace are below. The machine is primarily
working as a transparent firewalling bridge but also runs NAT, pf and
dhcpd for a 192.168.x/24. The freeze can often be provoked by obtaining
an IP in the 192.168.x/24 and immediately sshing from this network into
a Host on the bridged network part.
The machine is currently still sitting there, so if additional info is
needed please ask.
thanks,
Leon
