Hi,

What should I do with the following kernel error messages:

got bad cookie vp 0xd19d6bc0 bp 0xc61d72bc
got bad cookie vp 0xd1480180 bp 0xc616fbec

After grepping the source, I discovered that this was an NFS problem
(it's not really obvious from the message, is it?). I have two
machines involved, no more, with

server: FreeBSD 4.3-RELEASE #0: Mon Apr 23 13:04:32 CEST 2001

handstarted with
# /usr/sbin/portmap
# /sbin/mountd -r
# /sbin/nfsd -u -t -n 4

client: FreeBSD 4.3-STABLE #0: Wed May 16 04:41:06 CEST 2001

handstarted with
# /sbin/nfsiod -n 4
# sysctl -w vfs.nfs.access_cache_timeout=2

(both sequences taken from /etc/rc.network - no /etc/rc.d/nfs.sh start
unfortunately :( )

I then mounted with:

mount -t nfs -o nfsv3,tcp,intr,rdirplus,-r=32768,-w=32768 server:/path /mnt

Both machines have a 3com 905 ethernetcard (xl0), are on the same
100mbit switch, and are running 100baseTX full duplex. The client is
a faster machine then the server however (P3-933 vs. P2-400).
Both machines are otherwise very lightly loaded.

Should I loose some options? Should I disregard the message? I think I
get this message because I'm running an application that accesses
a lot of files in the same directory. Unfortunately, around the time
when this message occurs, the application also stops running, with
the job half done :(
