After upgrading my 1.17.1 server to 1.18 I started getting these errors.
happens every 15 minutes or so even with no mods loaded, just fabric.

Does this happen on a pure vanilla server? In order words, can you try reproducing this using a separate server instance of Minecraft 1.18 that is not modded in any way?
It seems more sporadic than I thought it was though. I only let it run for about an hour in vanilla . It's possible that it just didn't happen during that hour.
Last night I thought it might have stopped because it went 4 hours without happening but then it started again.
