A few days ago one of our admins accidentally spawned in 4000 mooshroom cows (/spawnmob typo). There are so many that whenever a player goes into the chunk with the cows, the server crashes. There is no way to killall/butcher them because the chunk in question only loads when someone is in it, and by that time it's too late because the server crashes immediately. Is there a way to wipe all mob data by editing/deleting some files via FTP, or some method like that? I'm not concerned about killing off legitimate mobs, I just want to kill everything to get rid of this problem.
