Hello Andy, > The reason is that xrootd cannot translate the NAS IP address back to the > DNS name. Are you sure the NAS boxes are properly registered in your name > server? The next version will give you an error message when this happens > instead of crashing. No, I am not sure. Do you know how I can check that? However is that something you expect with the new versions and not the older ones? If I use the older xrootd version then it works fine still. -- gregory > Andy > > On Tue, 22 Mar 2005, Gregory Schott wrote: > >> Hello, >> >> While I could xrdcp a file when running version 20050110-1339, running now >> version 20050321-0425 the xrd process crashes on the dataservers (RH7.3 >> and SL3). >> I appended below some logfiles, the xrd and olb logfiles don't say anything >> special and xrdcp complains for an error. >> The core file on SL3 says: (see below) >> >> -- Gregory >> >> >> # xrd logfile >> >> 050322 16:30:23 001 (c) 2004 Stanford University/SLAC xrd version >> 20050321-0425_dbg >> 050322 16:30:23 001 xrd@f01-001-116 initialization started. >> 050322 16:30:23 001 Using configuration file config/dataserver.cf >> 050322 16:30:23 001 Optimizing for 256 connections;
