I rather doubt it's a dCache bug, or well, at least it used to work in older kernel versions as mentioned in the original report. Also, as you say, dCache is purely in userspace. > Please do attach the full boot log, after having triggered the > problem. There are no additional messages after the condition has been triggered.

That's a bit difficult, as these are production nodes in use for WLCG, I could only try doing so when we schedule the next downtime. When I just retried I also noticed that after Ctrl-C-ing the hanging mv it seems that dest file is kept, and the src file is gone (which I'd consider as data loss, caused by this issue). Cheers, Chris.
