Server hard locked for two hours, I ran a warmroast and got this-
its_meow.betteranimalsplus.common.entity.EntityPheasant.onLivingUpdate()100.00%24100ms

Versions:

• Forge Version: forge-1.14.4-28.1.104
• MC Version:1.14.4
• Mod Version:betteranimalsplus-1.14.4-8.0.0

Hmmm... There is not much I can do to diagnose this issue since this seems to be just passing through the living update method, rather than executing the remaining code (any of my code)... something else is happening here.

thread is parked, means another thread is holding a lock, warmroast screenshot is only covering the main server thread. Maybe the server logs includes a dump of all threads?

@LemADEC is correct

Closing until someone can reproduce with an all-thread dump
