XFS causing stack overflow

To: xfs@xxxxxxxxxxx
Subject: XFS causing stack overflow
From: "Ryan C. England" <ryan.england@xxxxxxxxxxxxx>

I am looking for assistance on XFS which is why I have joined this mailing list.  I'm receiving a stack overflow on our file server.  The server is running Scientific Linux 6.1 with the following kernel, 2.6.32-131.21.1.el6.x86_64.

This is causing random reboots which is more annoying than anything.  I found a couple of links in the archives but wasn't quite sure how to apply this patch.  I can provide whatever information necessary in order for assistance in troubleshooting.

Thank you
