1. nfsd oops 2.4.19-pre10 and 2.4.18 xfs

Hello,

We're experiencing problems with a Linux nfs server. Client is
FreeBSD. Filesystem is big (150G, 3M inodes used) but not heavily used
over NFS, apache rather. This happens every few days. Client hangs.

I'd be happy to supply any aditional info.

Tomek
