Hi Christopher,
I think this is a case for Fabrizio.
Cheers,

Betreff: xrootd crashing within minutes after restart
Dear all,
at KIT we are experiencing the following problem: on two servers, xrootd
crashes all the time within minutes (usually <5 minutes) after restart.
The traceback always reads:

I have uploaded a dump to
http://www-ekp.physik.uni-karlsruhe.de/~jung/core.13189; we are using
xrootd version 2.9.1 build 20100510-1509.
Could you please have a look at it and help us to find the cause? Thank
you very much.
Best regards,
Christopher.
