It seems like you installed it or upgraded to it, then became "greatly concerned" for strange reasons. I really don't think you have anything to worry about. The only "gigantic" difference, as I see it, is that the ULE scheduler is now the default (while in 7.0, 4BSD was default). I personally run all of the above services (minus bind94, clamav, and snmpd; I use the base system bind, do not care for AV software, and use bsnmpd where applicable), and I also run all of those services on servers in my co-location. We have a RELENG_7 box which is working fine doing all of the above, on a dual-core processor to boot. > Actually there is one strange thing what I described here before -- > 'top' reporting incorrect process times.

Maybe it is not > just a good idea to have a 'scrub' rule on router... No, it's perfectly fine. But your description of the problem is too terse, and the issue should be discussed on freebsd-pf not here. There *are* other problems with pf which have been fixed in RELENG_7 (7.1), and you can review my Wiki to see what those are. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
