>Summary: make 5.1agent skip NFS mounts when traversing hrStorageTable

Initial Comment:
we have a little trouble with NFS mounts getting hung
and, notwithstanding server reboots, having a bunch of
processes in our clients' process tables getting stuck in
uninterruptible sleeps on the NFS stuff they were using
until the client gets rebooted. lamentably, snmpd often
falls prey to this, as it answers polls from nagios of
its hrStorage listing every few minutes. attached is
a patch that (perhaps kludgily) works around this. this
is to the source included in Red Hat's version of your
5.1.2 tree, so it may or may not apply to 5.3.1, but
you'd probably also need to make this configurable and
otherwise clean it up, so this is just maybe the germ
of an idea you can run with

thanks for the code. i wish we could run 5.3.1, but
we've got too many shared-library dependencies on
libnetsnmp.so.5

As for your shared library dependencies: you could keep the
old libnetsnmp*.so.5 (libraries only) and install the full
net-snmp 5.3.1 (with the agent) besides it. They both
shouldn't interfere too much.
