imo this is the best way to find whats crashing your server, and its what I do when my server crashes. Comment out all of your plugins, then restart the server. One its restarted and running, go into hlsw, put lal the server info in so you see the logs in the console, then uncomment all the plugins, and change the map via hlsw. In the console window, it will tell you what your missing.... usualy. It's always worked for me ;)
