Seems to happen about once per day. Destination is fine (NFS mount to NAS) and file seems to copy just fine regardless.

OSX is up to date and running Dockerized.

Oddly it's just really once a day despite maybe 5-10 new downloads a day. I can't see anything else obviously triggering (filenames are sane, no special chars, etc)

@medariox a race condition could cause this, as could a file being opened in the wrong mode (e.g. opened 'wb' instead of 'r'). This is happening in shutil_custom. The code I posted previously with changes to shutil_custom that used context managers for properly opening/closing files would likely fix this.

@labrys Do you want to PR it or should I do it?

[labrys]

Feel free to PR it. I'll review it if you would like.

@bobbysteel I assume you have already checked your permissions? Also are you sure it only happens once a day? Don't rely on the error count in the UI for the number of times it happens - many errors are only counted once until reset.

[a10kiloham]

Yep permissions fine and file copies fine. Grepping logs shows only one
line like this in each day or two
