Hi Andreas, I think that this is a consequence of missing socket files between xrootd and olbd processes. We had those problems when we use /tmp for the sockets files. That directory was purged constantly by the facility's external cleaning program. What is your adminpath ? We moved the adminpath to other location and no problems for now.
