Error deleting file (18.0.4)

Nextcloud version: 18.0.4
Operating system and version: Ubuntu 18.04
Nginx version: 1.14.0
PHP version: 7.2

The issue you are facing:
Getting error deleting file message when trying to delete file with web interface.
File is 3.5Gb has been uploaded via desktop client. Right after uploading (desktop app became green) i’ve tryied to move this file to another folder which was shared by other user. File has not been moved and the subj message appeared.
I successfully copied the file to the desired folder. But still can’t delete it from initial folder. I deleted it from local folder of my PC and desktop NX app already synchronized this folder. But the file still at its place.

2 hrs ago I did the same operation with another file (3.9Gb) and everything was fine.
Now if you upload some small file to the same folder then you can delete it with no questions.

And immediately update: while typing this message problem is solved! The file just disappeared.
I’ve tryied to replicate the problem:

  1. Renamed the same file and uploaded it via desktop app.
  2. Than opened folder in web interface and saw that the file is gone. There was only freshly uploaded new file.
  3. Freshly uploaded file was deleted with no troubles.

So it’s just a report about possible bug.

Is this the first time you’ve seen this error?: Y

Steps to replicate it:

  1. No idea.
