Unhandled exception when doing mass rename

[Qubits01]

Using Version 2.2.0 under Linux. command executed (repeatedly): ia move a/b.dat a/c.dat -H x-archive-keep-old-version:0

I'm batch renaming a few 100 files. They're pretty big and the directory is large, close to 1TB. Renaming takes several hours to finish. Anyways after renaming the first few dozen files, this exception pops up:
