I switched i386->amd64 on my server, with full new ports tree, 
save only configs. Under heavy disk IO, "Wired" memory increased and 
kernel panic in malloc inside IPFW. Uptime back proportional of disk IO load,
with transfer large files from one HDD to another,paniced from 1 to 3-4 hours. With no IO uptime about 2-5 days. It may be ZFS related problem because, 
I switch /usr and /var to ZFS. I try to fix problem by configuring ZFS in 
loader.conf, but nothing help.
panic always in:
ipfw_ctl() at ipfw_ctl+0xb4. 
rip_ctl_output() at rip_ctl_output+0x9f
start copying large size of data from UFS to ZFS or vice versa. "Wired" memory  increased value and after some hours value above 2GB then hang in malloc always in IPFW.
