This is a package from EPEL. Can they do something in the package to make it work without being blocked? In any case, my real question is whether this could be related to the system hang. I don't really see why a failing access in a perl script would be a real problem unless there is some more serious bug, so it may not be related at all. There were several such log messages, so at least we know the first few weren't fatal. -- Les Mikesell lesmikesell at gmail.com
