Hi there,
I was trying to copy ~15TB of LIGO public data to our local clusters Lustre filesystem and found that when using multiple streams with the -S option xrdcp could hang when connection issues occurred (there was a firewall "upgrade" that caused a lot of issues). When run without the -S option xrdcp would correctly eventually give up on copying and exit with an error.
Unfortunately this happened just before I had to head overseas for urgent family business and I only learned about this location to report issues on my return by a colleague overseas who suggested I open an issue about it, so I'm afraid I have no extra useful information to add. I did run pstack at the time to check stack traces but I'm afraid I don't have a record of them.
Host OS: CentOS 7.5
xrdcp version: 4.8.4
All the best,
Chris
