So, this is my first post, but not my first problem of this nature. It
just so happens that this is the first one with a recent kernel to give
useful data, useful enough to post it and seek some advice on the subject:
symptoms: machine gets high load, nfs mount processes hang, and things
(particularly NFS) stop working. ssh and ip connectivity still works, as
does ps.

It wasn't very old when we started testing it to resolve further NFS
problems about 6 weeks ago. It takes a while to get through the
necessary regressions to make sure things are generally ok before
getting comfortable with a rollout to more than a couple nodes. The
problems we experience are more of a statistical nature across nodes, so
we don't usually experience them until we have some mass of upgraded nodes.
We checked through the changelists and didn't see anything that stood
out as "ah ha, that's the problem". Most of the updates seemed to not
mention NFS at all. Do you have one a particular issue/patch in mind?
This is a NFS client mounting a server elsewhere. The ps listing shows
several stuck mount commands, which is another symptom of the general
issue. Let me know what else. Certainly it's possible to try another,
new kernel, but then I'll be posting about .36.1 in about 6-9 weeks and
chances are that it will be considered old. :\
Distro is Centos5.4 with updates. kernel is from kernel.org
