Pandas EmptyDataError While Fixing Interface Residues

Hi, I was running multiple runs parallelly on multiple GPUs with the same output folder and one of the runs exited with the error below when fixing interface residues.

The runs continued for more than 3 days without an error, and this error has only occurred once. Given the infrequency of the error, is it possible that it is caused by a race condition where one run tries to read a file while the other one is using it?

Traceback (most recent call last):

pandas.errors.EmptyDataError: No columns to parse from file

Start at bindcraft.py line 396, where pandas reads failure_csv, and inspect how that file is created and accessed when parallel runs share an output folder. Reproduce the shared-folder scenario if possible and determine what behavior should occur when the CSV is temporarily empty; done means the intermittent EmptyDataError is prevented or handled and the parallel workflow remains usable.
