[Users] problems with sparse errors with ploop

[Rene C.]

Suddenly getting these errors.  What can I do to fix it?  Already
tried Googling but not finding anything that seems applicable. It
mounts but everything is working really slow on this container and I'm
really out of my depth with this error!
