Server crashing

[MysteryManX93]

I'm using Tekkit Classic to make a production studio for filming. The problem I have right now is when I switch on my roof lights (also green screen lighting and other lights) the server crashes? Not sure if it's because of the amount of lights I'm trying to power, or if my computer just cant handle it.

As far as I can see, it looks like you havn't stopped the server for all changes/files to be saved. Simply stop the server, then start it up again. Then post back with the results
