I won't blame Roland, I'll blame myself.  The front of the rack sits on the right side of my computer console and facing me.  I probably "bumped" the patch cord plugged into the Octa-Capture headphone jack several times.  In a different position it would not have been in the "line of fire". 
 
But, fortunately, it was fixable. I did a recording session today and used it and no problems.  The new Studio-Capture came in and has been installed and checked out.  I'll be using that and the front panel does not protrude past the front of the rack like the Octa-Capture does.  A little "safer" in my installation.
