 We now have a stable machine without QUOTA *and* INET6.
 (only without QUOTA the machine died 24hours later). We left rpc.lockd
 running.
 
 Here is a simple zsh script to make it crash when with QUOTA-enabled
 kernel (use $(seq 1 50) or ? with another shell). launch it on a client
 and see 'top' on the server... I'm not kernel (nor nfs) hacker, but I
 may try some patches if it can help.
 
 mount options:
 /dev/da0s1g on /u (ufs, NFS exported, local, with quotas, soft-updates,
 acls, fsid e0bf4c447f5cf8a5)
 
 ---------------- crashlocks.zsh
 #!/usr/local/bin/zsh -x
 for i in {1..50} ; do
   lockfile truc$i &
 done
 ----------------
 
 Hope this can help...
