Today after restarting my server, my server's memory usage has nearly maxed out, as well as the swap file usage. No changes made and no one is logged in.

Prior to the 1.17 update, there wasn't a memory usage issue.

Server has 4GB Ram. Currently using 3.54GB with no one online. Before it was 2.5GB

Swap has slowly crept up to 334MB, before it was 8-12MB

Update: When stopping the world and starting swap and memory usage will max out and the minecraft process/console will crash. After I start the console again, it's seems to be more normal again.

I also switched back to our 1.16.5 map just to see if there was any difference. No change from switching.
