Hi,
I am not able to reproduce the problem in bbrprod01.
I sent a number of times commands like this:
bin/arch_dbg/xrdcp -d2 configure
root://bbrprod01:1094//prod/test_fabrizio1911-12/subskim/SPskims/test5/001237/200301/1008//a/b/c/d/e/f/g/h/i/arggghhh/a/b/c/d/e/f/g/h/i//j/
As you can see in /kanga/prod all my tests were successful.
Can you point me to a testbed where the things crash?
BTW, why are you used to write ////prod? (I tried this too)
Another thing. Has libXrdOfs on bbrprod01 been updated? The newest
versions are supposed to create new files with correct permissions with
the flags XrdClient sends.
