Deadlock avoided on Tahoe

Hello,

I am updated to Tahoe yesterday and Hazel 6.0.4 has stopped working on an iCloud to NAS rule. A rule that has been error free for months so I assume it is a Tahoe problem, but in case you need bug reports I figured I would post.

Rule runs on an iCloud folder and renames moves any files there to a NAS folder (Synology). The error is "The operation couldn't be completed. Resource Deadlock Avoided."

Log file below.

Thanks,
Lee

Unfortunately, that is a generic error provided by cloud storage plugins. Are you able to do the same operation manually in Finder?

Yes, I can do it manually. NAS and iCloud are both working fine as far as I can tell, I have been able to move files, etc as normal.

Try experimenting with using a local drive at either the source or destination to help isolate where the problem lies. If you have access to other cloud services (e.g. Dropbox) see if you get similar results there.

Sorry for the delay. It is working with all other rules, except files located on iCloud Drive.

It will move files to iCloud Drive though, just not off of iCloud Drive. I will see what else it will not do.

I have got the very same Probleme here. I cannot move or copy files from iCloud anymore. Worked fine before with Sequoia.

I have tried to spilt the Hazel rules into two rules. The first is doing a rename, which still works fine.

What makes me wonder is that it wants to use the documents folder, but my documents folder is not in iCloud, and the folder it shall move it is not within the local documents folder.

Did you give Hazel full disk access?
