I reported hard lock issues with ipfw+dummynet on other 7.0 (and 6.3), on FTP mirror i had to disable dummynet, but then there came out another deadlocks and i
don`t have the time and strength to debug everything from the beggining and to wait for solutions, while going to data center every few days to reboot machine
and in the end there is no solutions...

I think the main problem was the ZFS filesystem, while it looked evrything running smootly, every few days the filesystem refused to respond to every request,
and all IO processes were locked up. There were no other way to get the machine running but coldboot :( And ZFS was the only advantage in my eyes that FreeBSD
had over Linux when I had choosed the platform for FTP mirror. I know ZFS is still experimental and not ready for production use, but stil ... Maybe it heavy
depends on the HW configurations, chipsets, raid configuration,i don`t know but for me is FreeBSD 7.0 unusable. I give a try when 7.1 or maybe 7.2 come out.
