[Peter_Losher@isc.org: More freebsd.isc.org issues...]

[Mike Tancsa]

We had one system locking up with nothing in the logs.  As it was 
inproduction, I didnt have too much of a chance to track it down. I 
speculated it was some issue with not having IPDIVERT in the kernel while 
ipfilter and IPFW2 were in the kernel.  Adding IPDIVERT in and turning off 
NAT on ppp and letting ipnat do its work over the PPPoE connection did the 
trick to stop it from locking up.  The box has been small s stable since 
then.  This is from an Oct 2 snapshot.

The only other issue that comes to mind is tegge made a patch to allow 
maxim at macomnet.ru do a make -j64 work on a low RAM situation.  But that 
corrected panics, not lockups.
