Hi, at GridKa xrootd/olbd failed yesterday with the following error messages in the xrd log, but nothing in the olbd log. Suddenly, the "All managers are disfunctional" message appears and eventually all clients asking for files are deferred with the "No managers available" available message. 70417 14:27:36 9951 odc_Finder: All managers are disfunctional. 070417 14:27:36 9951 odc_SelectManFail: user=skimprod.16534:[log in to unmask] No managers available; wait 10 070417 14:27:36 9951 odc_SelectManFail: user=skimprod.25855:[log in to unmask] No managers available; wait 10 070417 14:27:36 9951 odc_SelectManFail: user=skimprod.10766:[log in to unmask] No managers available; wait 10 This went on until I restarted xrootd/olbd (no, didn't take pstack :-( ). Any ideas? At GridKa we are using version 20050920-0008. Cheers, Andreas
