I’m not sure if we found the actual root cause of this, bit we attributed it to an inflated cache_files collection in mongodb. This were artefacts remaining after we refactored our cluster lanes into a single cluster lane.
I believe we fixed it by stopping all cryosparc jobs, deleting the cache files entries from the db and removing all files from the cache directory and restarting Cryosparc. The issue has not reappeared since.
Currently (on v4.4.1), we’re facing a different issue, as discussed here Particles cache issues - #10 by ebirn
