Description Orion Poplawski 2006-08-01 11:43:59 EDT
Description of problem:

One of our FC4 servers has started hanging up each night since Jul 17 or so.  It
looks like it is related to disk/nfs access.  I'm attaching a system trace from
the most recent hang.  Looks like many processes are waiting for io related
locks held by a couple nfsd and smbd processes.  Unfortunately it looks like the
trace may be incomplete as I don't seem to see any trace info for the process
supposedly holding the locks.  Let me know if there is anything else I can try
to debug.

Version-Release number of selected component (if applicable):
2.6.17-1.2142_FC4smp

How reproducible:
Every day

[This comment added as part of a mass-update to all open FC4 kernel bugs]

FC4 has now transitioned to the Fedora legacy project, which will continue to
release security related updates for the kernel.  As this bug is not security
related, it is unlikely to be fixed in an update for FC4, and has been migrated
to FC5.

Please retest with Fedora Core 5.

Thank you.
