Subject: hung server

I have a linux NFS server running base 2.4.18 with xfs patches from SGI.
Seeminly random times, the nfs server will become unresponsive. On
a client, doing showmount -e [server] will timeout. Looking on the
server shows that the nfs daemons will go into the DW state as shown
by ps:
root 123 0.2 0.0 0 0 ? DW Jul25 2:53 [nfsd]
root 124 0.2 0.0 0 0 ? DW Jul25 2:50 [nfsd]
root 127 0.2 0.0 0 0 ? DW Jul25 2:52 [nfsd]
root 128 0.2 0.0 0 0 ? DW Jul25 2:52 [nfsd]
root 129 0.2 0.0 0 0 ? DW Jul25 2:53 [nfsd]
root 130 0.2 0.0 0 0 ? DW Jul25 2:53 [nfsd]
root 131 0.3 0.0 0 0 ? DW Jul25 2:55 [nfsd]
root 132 0.2 0.0 0 0 ? DW Jul25 2:53 [nfsd]

The load will sit at about 8 which is how many nfsd's that I have
running. I thought this was usually caused by a hardware problem, but I
am able to get the the local filesystems that are exported just fine.
Any help would be appreciated.
Thanks

This sounds the same as the problem I reported - see:

http://marc.theaimsgroup.com/?l=linux-nfs&m=102579958731319&w=2

and the thread at:

http://marc.theaimsgroup.com/?l=linux-xfs&m=102579948531207&w=2


I've only just upgraded to a 2.4.19-rc3 + XFS CVS kernel, so I don't
know yet if the problem has been resolved...
