Very slow upload and processing of files in Mayan Docker

Hello,
We are testing the Mayan / Docker installation. Everything works fine but the file upload can take up to 24 hours to complete. This happens regardless of the server workload. Even if there is only one file in the queues, it takes a whole day to complete.
Restarting the docker *_app container solves the problem immediately and the files show in the GUI. Unfortunatelly, this is not a viable solution for end users.
I already increased the number of concurrent workers through the configuration file, but nothing seems to change.
Any ideas? Thanks for your help.
