Following on from WINDUP-2620 the following has been proposed to improve the user experience with regard to running the Web UI on a MAC and setting the ulimit appropraitely:

Looking at our earlier issue notes:

1. we should think about which is the real minimum number we need to set
2. add a note to docs about when to increase it
3. test what happens when number is too low
4. give a speaking error message

Do we have an answer to

#1 How many files does MTA need when analyzing large sets of apps/files, and will 5000 be enough? (we could have a small service on wildfly that periodically lists the number of open files, or maybe outside of the process an OS query of open files by the process in a loop).

--> should probably be a separate Jira for hosted version.

#2 If it could run over, we should add a hint in the docs so people know where to change it.
