I remember being on the Leviathan one time, and 4 judges attacked me all at once. Yes, I share your pain
On the ship, some people trip the alarms on purpose so they can have more soldiers to fight in order to gain more EXP, LP, and items. They just keep coming after you if you do this as you said.

During a time while the alarms are on the whole time, some even stay for a while constantly fighting soldiers for LP. These people are usually a bit higher leveled, though (they generally had leveled a bit at the beginning). If I were to try chaining soldiers at this point, the sound of the alarms would get quite annoying.
I used the alarm to get the soldiers to come to me, that way I could easily gain EXP and LP. But after about 99 soldiers they will stop coming, it is a great place to gain levle in.
