We aren't running Red Hat.  We have:

CentOS release 5.2 (Final)

The rogue files don't stay around long enough to stat() on all nodes.
My assumption is that these are files just created or in the process of

I wasn't too concerned since this doesn't seem to have any negative
impact on the application, but was curious nonetheless.
