This is mainly happening in my test world in peaceful mode, errors described below are caused by mob spawners as there are no mobs spawned in the world.

These are the only errors in the logs and the logs are huge.

the game freezes, then crashes randomly. specific ares seem to trigger the crash more frequently than others but nothing in the logs other than below messages.

is there a way to get more verbose logging?
