All your traces seem to have in common that you're block on locks hold

better directly 2.6.3-rc6?

I would be surprised if this is something inside XFS, but running with
CONFIG_XFS_DEBUG never hurts.


Christoph,

Thanks, running with DEBUG and 2.6.31-rc6.

CONFIG_XFS_DEBUG=y

So far the problem has not surfaced, but it normally takes 24-48 hours.

Justin.
