Hello. I have a bunch of Linux (2.6.18-128.1.1.el5, RHEL 5.3) boxen that
mount NFS shares from Solaris, and one died recently in a conflagration
of kernel segfaults following an NFS error:
Sep 11 19:37:12 nubar6 kernel: NFS: Buggy server - nlink == 0!

Perhaps the Solaris NFS server is indeed buggy, but shouldn't this be
caught/handled by the Linux NFS client? Any thoughts/suggestions?
Thanks!
