Hello Miriam,
I am forwarding your mail to the xrootd mailing list.
The problem Miriam has is that when she uses xrootd the request fails
and the redirector babar2 is crashing.
I have restarted xrootd (but didn't find the core although 'ulimit -c'
says unlimited...) ?????
Then I tried on babar and babar2:
KanCopyUtil -r -n 20 /store/SP/R12/000998/200301/12.6.0b/SP_000998_011885
and had no problem... (no crash)
What command are you using? Are you running in batch? What I find strange
is that I seem to be logged from a different machine. I tried to ssh
babar2 then I ask csh -l and do the KanCopyUtil and in the xrd log I see
"User logged in as schott.28977:[log in to unmask]" which seems to
be babar.fzk.de!? but env | grep HOST confirms I am on babar2 ?????
I see in the logfile for you:
