Hi Pete, Sometimes minor things leak in that have major impacts. Usually I go by what is really running successful elsewhere to determine the probability of success. However, you do bring up a good point. Chris, please make sure that you are using -w on the olbd consistently with -t on the xrootd data server. If you specifu -w but not -t then you will see exactly what you described. Also, the logs during start-up time to hang time would be helpful (i.e., redirector: xrootd and olbd, and data server xrootd/olbd). Please clearly identify which is which. Thanks.
