Folia version

This server is running Folia version 1.21.11-11-ver/1.21.11@e112b00 (2026-01-20T18:53:05Z) (Implementing API version 1.21.11-R0.1-SNAPSHOT)

Other

I started using Folia around one month ago. Since then, randomly about once every 1–2 weeks, the server stops due to this issue.

It is not a crash, the server automatically stops itself when the error occurs.

Start by reviewing the linked stack trace and the Folia 1.21.11-11 server version in the report. Compare the shutdown event with the reported threading issue, then establish a reproducible trigger or isolate the responsible condition; done means the server no longer stops automatically under that condition.
