Confirmed
Hostile mobs rapidly despawn and respawn repetitively when you're about 125 blocks from the ground. This is easiest to see in the End.

Squid spawning causes server to lag.
Steps to reproduce:
Render Distance > 16 chunks
1. Fly high above an ocean around height of 200.
2. Wait at least a minute.
3. Fall down and see squid spawning and despawning rapidly everywhere
At height 200 above a level 46 ocean, the server becomes laggy. The longer you stay above the ocean, the more the squid lag seems to "accumulate". Eventually the lag will dissipate and the squid spawning will go back to normal. An aqua affinity helmet will help you see all the squid spawning/despawning
These error messages start to pop up if you stay at the 200 height for a while(10 minutes or greater). While an indicator of general lag, the server is fine any other time except when at 200 height above ocean.
