------------------------------------------------------------
[~cziegeler]
Thanks a lot for your continuous support. I had a thorough testing locally
where our management agent started installing the configurator and the
exception occurred a few times. After delving deep into it, I strongly believe
it is not due to concurrency issues where multiple threads accessing the
internal data, it is due to the same thread trying to modify the map(s) while
iterating it (as suggested by [~laeubi]). I think your fix should solve the
problem.
What do you suggest then? Should I close the PR?
