Due to some update that came through NFo, the server was repeatedly crashing. Seems to be running out of memory, but I still have to do some research on which plugins need to be fixed.
At this moment, the server is running the most up to date game version without any bukkit plugins, which is 1.7.2. I assure you this is a temporary measure--the map we had will be back, no worries. Might be a week or so till I have time, since I'm traveling Fri-Sun.
