Hi Andy, I just played the game of removing all normal messages from the redirector logs to see what remains. On one of the redirectors at SLAC there was one message which I didn't recognize: bbr-olb04> cat /var/adm/xrootd/logs/xrdlog | grep -v "asked to wait" | grep -v redirected | grep -v login | grep -v " disc " | grep -v "xrootd protocol anchor trim done" 050328 00:00:00 059 (c) 2004 Stanford University/SLAC xrd version 20050321-0425_dbg 050328 02:14:08 097 odc_Locate: polci.3440:169@noma0080 got no response from bbr-rdr04 path=/store/PR/R12/AllEvents/0002/42/12.3.4e/AllEvents_00024239_12.3.4eV00_C14.2.0bV01.01.root bbr-olb04> The full history for this client process is in (a) below. It _looks_ like the client was subsequently properly redirected for that file (and he came back to ask for another file 21 seconds later, so the application didn't exit with some error either). What does the "got no response from bbr-rdr04" message mean?
