Alarming amount of "Exception in thread" errors in server log

I added Distant Horizons to our All The Mods 9 server but our server log is getting spammed with: "Exception in thread "DH-PriorityTaskPicker Thread[4437]" java.util.concurrent.RejectedExecutionException: Task com.seibel.distanthorizons.core.util.threading.PriorityTaskPicker$TrackedRunnable@2a107abb rejected from com.seibel.distanthorizons.core.util.threading.RateLimitedThreadPoolExecutor@2e1acf5d[Running, pool size = 4, active threads = 4, queued tasks = 4, completed tasks = 14298] at java.base/java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2081) at java.base/java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:841) at java.base/java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1376) at TRANSFORMER/[email protected]/com.seibel.distanthorizons.core.util.threading.PriorityTaskPicker.tryStartNextTask(PriorityTaskPicker.java:78) at TRANSFORMER/[email protected]/com.seibel.distanthorizons.core.util.threading.PriorityTaskPicker.access$200(PriorityTaskPicker.java:17) at TRANSFORMER/[email protected]/com.seibel.distanthorizons.core.util.threading.PriorityTaskPicker$TrackedRunnable.run(PriorityTaskPicker.java:217) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1144) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:642) at java.base/java.lang.Thread.run(Thread.java:1583)" Would anyone have an idea of what could cause this?

I am getting the same error permanently I have no idea what caused it, it started a while after trying to generate some areas of the world via pregen command. I tried resetting DH somehow but i dont know exactly how and why this is happening / fixed (also I am on Forge 1.20.1)

does it happen on a fresh world with ATM9?

for me it was a chunky pregenerated world (not atm9 but custom modpack, worked fine for ~10gb of sqlite data and then it started with the errors. Generation and displaying chunks still works but pregen command doesnt i believe + permanent spam
