>Environment:

-current NFS client, with 2.2.5 nfs server

>Description:

My nfs server had mountd die, and the client rebooted. It couldn't mount
what it needed to from the server, but apparently kept trying in the
background. After I restarted mountd on the server, all was well, except on
the client:

/dev/wd0s1a on / (NFS exported, local, writes: sync 24066 async 42211)
procfs on /proc (local, writes: sync 0 async 0)
home.internal:/home on /home (writes: sync 0 async 0)
home.internal:/var/mail on /var/mail (writes: sync 0 async 0)
home.internal:/home on /home (writes: sync 0 async 0)
home.internal:/var/mail on /var/mail (writes: sync 0 async 0)
home.internal:/home on /home (writes: sync 0 async 0)
home.internal:/var/mail on /var/mail (writes: sync 0 async 0)
home.internal:/home on /home (writes: sync 0 async 0)
home.internal:/var/mail on /var/mail (writes: sync 0 async 0)
home.internal:/home on /home (writes: sync 0 async 0)
home.internal:/var/mail on /var/mail (writes: sync 0 async 0)
home.internal:/var/mail on /var/mail (writes: sync 0 async 0)
home.internal:/home on /home (writes: sync 0 async 0)
home.internal:/home on /home (writes: sync 0 async 0)


>How-To-Repeat:

kill mountd on server, and make client keep trying to mount something in the
background with mount_nfs -b..... Apparently it buffers a few requests up,
and they all succeed after a while.

>Fix:
	
No clue, but it appears to be harmless.
