Stange NFS messages - 2.2.18pre19

Stange NFS messages - 2.2.18pre19

[Sasi Peter]

Hi!

I'm getting this under moderate NFS load:
Nov  6 17:39:56 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  6 17:40:08 iq kernel: svc: unknown program 100227 (me 100003)
Nov  6 19:06:11 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  6 19:38:48 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  6 19:54:51 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  6 20:08:53 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  6 20:53:23 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  7 09:03:28 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  7 09:15:18 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  7 11:12:51 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  7 18:01:17 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  7 19:34:59 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  7 19:40:59 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)
Nov  7 21:43:48 iq kernel: svc: server socket destroy delayed (sk_inuse:
1)

What do these means? Is this a kernel bug?

Your Suns are using TCP mounts, this got introduced into 2.2.18
somewhere and is a bit broken, do a patch -R with
ftp://oss.sgi.com/www.projects/nfs3/download/nfs_tcp-2.2.17.dif and
these go away.  Suns try TCP mounts first.  Be careful to unmount them
first or they will hang waiting for the TCP server to come back up.

I really really think this should be backed out -- or at the very least
disabled. The code wasn't part of the dhiggen merge, it wasn't tested,
and it doesn't work well. Heck, it's still experimental and not recommended
in 2.4.0-test.

What's worse, it will burn everybody out there who is using am-utils or 
an automounter that tries TCP mounts first. NFS/UDP server support in 2.2.18
is so much better than in previous versions, it would a shame to ruin
it with this ill-fated patch.

Its now an experimental option in my pre21 build tree. So people can play with
it and debug it if they wish
