Users may receive an error when using the chgrp command on data in /fs/ess/ locations.

$ chgrp -v PEX1234 my-file.txt
chgrp: changing group of 'my-file.txt': Disk quota exceeded
failed to change group of 'my-file.txt' from PEX0001 to PEX1234

This is a very infrequent issue and OSC have identified a workaround.
