Hello,
Does s/o have an idea as of why xrootd would crash on the SL3 redirector
when adding the SL3 GPFS to the already running RH72 NAS boxes pool? I
installed on GPFS the september SL3 binaries. I have the following olb
logfile on the dataserver (the crash is silent on the redirector).

I also added two lines on the config file for the 2 new GPFS (see full
dataserver config file below):
olb.allow host f01-010-110.gridka.de
