Bug description

When uploading a bunch of pictures to a shared folder, there were a lot of "An unknown error has occurred" errors. In the logs, I see GenericFileExceptions (from App "Index") and corresponding PHP errors ("Failed to open stream: No such file or directory", see below).

Steps to reproduce

1. Create folder, share it
2. Upload files
3. "An unknown error has occurred"

Expected behavior

no error should occur

When did this behavior start? (i.e. right after an upgrade? etc.)

Does /var/www/html/data/appdata_ocwflvc6mxkf/preview/b/b/f/9/6/d/e/46219/256-256-crop.png exist in your container?

"GET","url":"/index.phpiew?

Do your URLs really have phpiew in them?

Run into this error every time I try to upload many files at the same time or a very large file (about 20GB). And the most interesting thing is that the threshold of getting this error is higher when I try to use a faster SSD. For example, I tested on a WD Black P10 HDD and the largest file I could upload was about 8GB, uploading any files larger than this would cause the error. Then I moved the data folder of nextcloud to a Samsung 980 SSD without modifying any config, and now I can upload files around 15GB.

Here are the error logs I got, as you can see, there are always two logs items for one failed uploading:

"无法打开文件" means "Cannot open file"

Here's one extra clue: I monitored the "Time Spent Doing I/Os" chart on my grafana, and found there's a huge disk reading peak after receiving the file chunks.

• I don't know when it started - I usually don't upload much files at once. I did update to 29.0.10 shortly, but I can't say if it's related.
• The folder /var/www/html/data/appdata_ocwflvc6mxkf/preview/b/b/f/9/6/d/e/46219 exists, the file 256-256-crop.png not at the moment.
• phpiew sounds strange, doesn't it? But I have no clue, where this URL comes from - I only found it in the logs...

I saw just now, that the log entries are not generated when uploading, but when opening a folder with pictures in Files, but not for each picture.
Unfortunately I'm not able to assign a specific log entry to a certain picture.
