freebsd stable - Apr 2005 - strangeness about netstat -m and mbuf clusters

Hi everybody,

I have something real strange about netst -m in RELENG_5:

caipi# uname -a
FreeBSD caipi 5.4-STABLE FreeBSD 5.4-STABLE #11: Tue Apr  5 13:18:21 CEST 2005  
root@hudson:/usr/obj/usr/src/sys/APP  i386

caipi# netstat -m
463324 mbufs in use
4294964312/25600 mbuf clusters in use (current/max)
0/4/6656 sfbufs in use (current/peak/max)
109863 KBytes allocated to network
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
323 calls to protocol drain routines


On all the machines where this happens I also see, that I cannot use vi 
to edit a file on an NFS filesystem. vi simply does nothing, it hangs 
and cannot be killed or only after a long time. Using truss is not 
possible: "truss: PIOCBIS: Inappropriate ioctl for device" (procfs is 
mounted). Using another editor (vim for example) works as expected.

Any ideas, what I could test/do?

Greetings, Oliver

See the errata for 5.3, this is still true for later versions.

Sounds like rpc.lockd is not set up on client and/or server.
