Hi Andy,
okay, we got another one. Here's the info.
The core file is in /var/spool/xrootd/se/ :
-sh-4.2$ ls -aos core.62610
4715952 -rw-------. 1 xrootd 7023529984 Mar 23 23:10 core.62610
And the gdb output:

Does this help? Let us know what else we can do to debug further.
xrootd seems to continue to run fine, and there haven't been many
of these 'already opened by 1 writer' errors, only 5 or 10 per day,
so that's good.
Thanks,
Horst
