The issue you are facing (with activated file-locking):

Uploading large files fails with error "MOVE url/dav/uploads/USER/web-file-upload-feez62946243t/.file 423 (Locked) (console)

After deactivating file-locking in config.php, the file upload works but a error is still displayed in the GUI (not console).

Is this the first time you’ve seen this error? (Y/N): No, it happens often while uploading large files (larger than about 20GB)

Steps to replicate it:

  1. Uploading files larger than 20GB

We have tried the following things:

  • disabling file-locking → file gets uploaded, but error message in GUI persists

  • disabled chunking (value 0) and increased apache2 header size

  • Apache2 Timeout → Timeout 600 (vhost)
    -SSLRenegBufferSize set to 1048570
    → Upload gets completely stuck after a few minutes

php.ini
max_input_vars = 100000
max_input_nesting_level = 128
default_socket_timeout = 180
max_execution_time = 10000
max_input_time = 10000
opcache.max_accelerated_files=100000
post_max_size = 40000M
upload_max_filesize = 40000M
max_file_uploads = 100

apache2.conf
(nano /etc/apache2/apache2.conf)
Timout 2400

chunksize set
sudo -u www-data php occ config:app:set files max_chunk_size --value 104857600

CONFIG.PHP:
filelocking.ttl": “43200”

Has anyone an idea how to fix this issue?

Thanks!
