This is the error given, it happens out of nowhere and logs don't show any errors that signify why it's happening

Random crashes keep occurring randomly not when a certain command is executed. This is stopping me from being able to get other players to join the server. It is also stopping me from wanting to buy a plan in the near future. The disconnect message also doesn't have any guidance of what I should do. It could be a plugin, but when the server crashes it's at random when certain ones don't have any influence. Is there any staff that might have knowledge of what's happening?

I'm trying to make a random ore generator for a server when cobblestone forms. I've found a couple skripts but none seem to work. This is the skript on block form of cobblestone: chance of 50%: set event-block to diamond ore stop chance of 3%: set event-block to gold ore stop chance of 5%: set event-block to iron ore stop chance of 10%: set event-block to coal ore stop chance of 0.5%: set event-block to emerald ore stop chance of 1.2%: set event-block to redstone ore stop chance of 1.2%: set event-block to lapis lazuli ore Can anyone find a working one for this current version?
