Hi Doug,

All of these core dumps indicate that you have run out of memory. It's no 
wonder that you get SEGV's at that point. How many sources are you using for 
this test?

Andy

Subject: [bug #88259] seg fault with xrdcp extreme copy


Follow-up Comment #16, bug #88259 (project xrootd):

Hi

  Here are more core files and log files from the failed
transfers of the Nov 1st version of xrdcp2

http://ascnfs.hep.anl.gov:2080/xrootd-federation/xrdcp2_Nov-1_core.24393
http://ascnfs.hep.anl.gov:2080/xrootd-federation/xrdcp2_Nov-1_core.24393.log

Have a look at the log it has an interesting error message in it.
the Machine has lots of memory 24 GB so I did not see a lot of swapping

http://ascnfs.hep.anl.gov:2080/xrootd-federation/xrdcp2_Nov-1_core.27823
http://ascnfs.hep.anl.gov:2080/xrootd-federation/xrdcp2_Nov-1_core.27823.log

and finally

http://ascnfs.hep.anl.gov:2080/xrootd-federation/xrdcp2_Nov-1_core.29125
http://ascnfs.hep.anl.gov:2080/xrootd-federation/xrdcp2_Nov-1_core.29125.log


Enjoy,

Doug

Please let me know when there is a new version of xrdcp to test
so I can thrash the system once again.
