read-only also in 4.1
# sysctl -w kern.ipc.nmbclusters=2048
sysctl: oid 'kern.ipc.nmbclusters' is read only
# sysctl -w kern.ipc.nmbufs=8192
sysctl: oid 'kern.ipc.nmbufs' is read only

yep, me, too, can't see exactly what postfix is bitching about:
# netstat -m
367/960/4096 mbufs in use (current/peak/max):
189 mbufs allocated to data
178 mbufs allocated to packet headers
150/504/1024 mbuf clusters in use (current/peak/max)
1248 Kbytes allocated to network (31% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
If you learn something, let me know, please. Thanks
