## Description

### Feedback:

While migrating large project from Jira to OpenProject (more than 3000 issues), we reach error links to attachments: "The attachment could not be created" or "Too many open files". It's appear that default Docker-compose installation have low Linux '''uLimit -n''' at 1024 open descriptors. We up it around 60 000 which unlocked some of our migrations of projects.

It may be interested to either up the default value in the Docker-compose default installation and/or to update documentation or error message in order to guide toward this Linux configuration.
