After startup of Nexus, you will be prompted with an error message regarding to increase the actual file limit:

If the fix for this issue has been merged, can the issue be closed?

[SchlegelS0208]

Yeah, should be fine. :)

In the mean time I fixed some other things too. There's a chance that I provide another merge-request in the next week.
