Minecraft Server Crashes with SIGBUS Error in OpenJDK 21.0.7 (No Errors Preceding Crash)

[Chrigux]

Describe the problem

I'm encountering a fatal crash in a Minecraft server running within the itzg/docker-minecraft-server Docker image. The crash occurs with a SIGBUS (0x7) error in the Java Runtime Environment (OpenJDK 21.0.7), specifically in the VM Periodic Task Thread during the PerfLongVariant::sample() function. Notably, there are no errors or warnings in the Minecraft server logs immediately preceding the crash, but creating a hs_err_pid1.log file in the data directory. The server terminated unexpectedly after approximately 5-6 hours of uptime.

This happens very few days.

No service logs after this until the crash at Fri May 16 01:17:38 2025 with the crash generating an hs_err_pid1.log file -> attachment hs_err_pid1.log

Manual restart the next day:

This seems like something to report to Mojang. After setup of the files this image simple executes the server jar.
