Follow-up Comment #1, bug #81162 (project xrootd):
Hi all,
I have come across the same error on an fresh ALICE installation
(xrootd-vmss_1.8b-1) under heavy load (the system has ~240TiB of almost free
capacity, so it receives continuous 2Gbit data stream. The error is
reproducible, but it only occurs after ~10hours of running. We don't see this
error on any other xrootd nodes (but they don't receive this load since they
are already full).
Would a gdb trace log help?
System info:
