Hello Fabrizio
I am running 20 xrdcp clients against a single xrootd server.
The command is:
xrdcp root://oprserv04:2094////prod/testFiles/dummyFile_15.df - | wc -c
The xrootd version was build from the head yesterday morning.
Every few hours I get a core which shows the following:
(gdb) where
#0 0x0095517c in memcpy () from /lib/tls/libc.so.6

(gdb) quit
Unfortunately I don't have the xrdlog file and can't tell you if something
happened on the server side, but I can repeat the test.
Any idea?
Cheers,
Wilko
