Why is my Server Crashing?

After I made some tweaks to my server(e.g: kit on spawn, setting up new player spawn point and default spawn point), whenever I run it, and log on to it, it crashes shortly after.

• I'm not entirely sure about the last one.

 

Error in ObsidianDestroyer and ClearLag ...
