Back in early 2006 I reported persistent hangs on the NFS server,
whereby all of a sudden about ten minutes after boot my primary NFS
server would cease responding to NFS requests until it was rebooted.
<http://www.ussg.iu.edu/hypermail/linux/kernel/0601.3/1631.html>
That time, the problem vanished when I switched to NFS-over-TCP:
<http://www.ussg.iu.edu/hypermail/linux/kernel/0601.3/1773.html>
Well, I just rebooted --- post-glibc-upgrade from 2.5 to 2.6.1, no
kernel upgrade or anything, so this bug has been latent during at
least my last three weeks of uptime. And it's back. (I've been
seeing strange long pauses doing things like ls, and I suspect
they are related: see below.)
/proc/sys/nfsd/exports on the freezing server:

I turned on ALL-class nfsd debugging and here's what I see as it freezes
up:

Looking back in the log I see intermittent malloc failures starting
almost as soon as I've booted (allowing a couple of minutes for me to
turn debugging on):

A while later we start seeing runs of malloc failures, which I think
correlated with the unexplained pauses in NFS response:

Fifteen minutes after that the whole thing seized up with malloc
failures as the only response.
We've obviously got some sort of resource leak (although why it's
suddenly appeared I have no idea). There's buckets of memory, though.
The system's not swapping or under especially high memory pressure
(indeed as I've just rebooted it and hardly started anything but the
usual daemon swarm and LVM/MD stuff, it's under rather *low* pressure by
its standards). (Dumps of /proc/meminfo, /proc/zoneinfo and
/proc/slabinfo below.)
I note that this error can be caused by both ENOMEM and EAGAIN, and that
there are numerous points in fh_verify() whose failure can lead to this
error. I'm just instrumenting them now so I can tell which is failing.
