Do you have FastASyncWorldEdit instead of the normal one? Is it updated? Try using https://www.mc-market.org/resources/5838/ stops a few Hacked Clients from crashing server. Also check if any plugins are causing stupid amounts of lag when a player uses them! More info/logs would be nice.

Are they DDoSing your server, if they are. Go find a host that provides better DDoS protection

Do you allow users creative mode?
Do you allow have any expensive (processing power wise) commands that can be run by users?

Edit: It might also be possible for them to lag it with redstone. Not 100% sure

You could use ClearLagg to find the chunks that cause a lot of lag.
