One server crashes on 1.17

This one server crashes 60 seconds after completing startup. This started occurring this morning, but my Turnkey (Stretch) MineOS HyperV VM has been running 16.0.1 OpenJDK for over a month. After banging my head against the wall for several hours, I spun up a new Buster VM and updated Java to 16.0.1 OpenJDK. This server runs fine on 1.16.5, and other servers seem to run fine on both 1.16.5 and 1.17. Any ideas?

java version

in the server.properties try to increase the variable “max-tick-time”. I set mine at 60000000 to allow for really slow ticks, but you may set it lower to catch hung processes earlier. I also have a problem with forced shutdown with the standard tick time.

That kind of solved it, thanks. It stays running now, but falls way behind at times. My daughter suspects they have too many mobs and is going to try to fix it. Not sure why the same world would run fine on 1.16.5 and bog down so hard in 1.17, but it is. This HyperV VM has 6 CPU Zen 2 cores assigned and 16gb of memory, and it certainly isn’t getting close to using that allocation.
