Server Shutting Down

Hi, my friend and I are having issues with the 1.7.10 pack and starting our pre-existing server. We were playing the 1.7.10 pack when the server seemingly went off for no reason, we weren't interacting with anything at the time but the server went down. After we have tried to restart the server many times and the issue persists. This issue has been happening for about 5 days now and we can't seem to find the reason behind the server crashing, occasionally we will start the server and it will launch then immediately crash. Other times the server will go from "Starting..." to "Stopping..." before the server even properly launches. I have viewed the logs and viewed the console a few times whilst attempting to launch the server and there doesn't seem to be any errors while launching, except for one time when it said GalactiCraft was giving an error. But that has yet to re-appear. We are not aware of the issue causing this and would like some assistance in diagnosing and fixing the issues. Thank you.
