      Description

      During stress testing of ligo.osgstorage.org I had a couple of instances where all the application processes got "Permission denied" after running for a long time.  The debug log only said "Failed to open status file."  After modifying the debug message to include the errno and reproducing the problem I found out that it was errno 2 "No such file or directory" and realized it was because the session leader process (which was my ssh login shell) had simply died.  I think it would be helpful to add a message to /var/log/messages explaining that authz failed because the session leader process of a user disappeared.
