Honestly, I'm not sure. I ran memtest and increased the swap size on Linux (thinking it could help with virtual memory pressure), and neither of them reported any issues.
Right now, the server is running fine, but I expect the crash to come back eventually — it usually happens after something changes, like updates to Crafty, Paper, or other components. If I don't update them quickly, I often get weird crashes. Then I update everything, the issue still persists for a while, and after hours of troubleshooting… it magically fixes itself. I’m not an expert in JVM internals — most of the ideas I try come from GPT or DeepSeek suggestions. I’ll try -XX:TieredStopAtLevel=1 and keep you posted if the crash happens again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2114521 Title: 🪲 JVM Crashes (SIGSEGV) with Ubuntu's OpenJDK 21 inside container running Minecraft server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-21/+bug/2114521/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
