Hello All,

Why on AMD64 kern.ipc.nsfbufs always zero:

# sysctl kern.ipc | fgrep nsfbufs
kern.ipc.nsfbufsused: 0
kern.ipc.nsfbufspeak: 0
kern.ipc.nsfbufs: 0
# netstat -m | fgrep sfbufs
0/0/0 sfbufs in use (current/peak/max)
0 requests for sfbufs denied
0 requests for sfbufs delayed
# uname -srim
FreeBSD 6.0-RELEASE amd64 GENERIC

Is this mean, that on amd64 nsfbufs have no limit?

amd64 and ia64 neither need nor use nsfbufs. See
