Cryosparc wrongly uses headnode as cache

Hi, all:
Though we have assigned cache in GPU node, we found cryosparc create a folder named ’ ’ (just a space) under cryosparc_worker folder, and then use this folder as cache. We found this problem half year ago and reinstalled cryosparc. It works normally for 1 months, then the problem comes again.

Does any one know the reason? Thanks in advance.

What’s inside that directory (ls -al ' ')?
And what is the output of:
cryosparcm cli "get_scheduler_targets()"
