[cups] CUPS filled up /tmp

[Rick Cochran]

Michael,

After the fire drill required to increase the size of /tmp to prevent this from happening again, my management is interested in an analysis of what happened.  This failure caused about one hour of downtime on a production system with one of our highest printing volume times of the year coming soon.  Fortunately, all Windows printing is done through a different system, and most OS X printing has not yet migrated to this CUPS server.  Plus it happened on a Sunday afternoon.

I run a vanilla RHEL CUPS environment with no custom backends, etc.

I appreciate your expertise and good will, but I really don't see how those files could have been created by anything other than CUPS.

Yours,
-Rick

It was PostScript.

The CUPS queues on this system send the print jobs to another server using LPD protocol.

Rick,

Those file names don't correspond to anything CUPS would produce... What are the contents of the files?
