Public bug reported:
Hi,
I’m running a Minecraft server using Crafty Controller on a Debian host,
but the Crafty container uses Ubuntu’s OpenJDK 21,
and the JVM is constantly crashing with SIGSEGV errors in random runtime stages.
Environment:
- Host OS: Debian GNU/Linux
- Crafty container base: Ubuntu 24.04
- Java version inside container:
OpenJDK Runtime Environment (21.0.7+6-Ubuntu-0ubuntu124.04)
OpenJDK 64-Bit Server VM (build 21.0.7+6-Ubuntu-0ubuntu124.04, mixed mode,
compressed oops, tiered, g1 gc)
- Application: Minecraft server (Paper 1.21.4)
- Java command:
java -XX:-TieredCompilation -XX:TieredStopAtLevel=3
-XX:+UnlockDiagnosticVMOptions -XX:CompileCommand="exclude
net/neoforged/srgutils/InternalUtils loadTinyV2" -Xms2G -Xmx8G -jar
paper-1.21.4.jar nogui
Crash logs:
Crash 1:
SIGSEGV at pc=0x00007fc33c129d71, pid=122, tid=185
Problematic frame:
V [libjvm.so+0x655d71] Compile::identify_useful_nodes(Unique_Node_List&)+0x131
Crash 2 (after tweaking flags):
SIGSEGV at pc=0x00007fe6635021ec, pid=104, tid=275
Problematic frame:
V [libjvm.so+0x8d61ec] IndexSetIterator::advance_and_next()+0xbc
Sometimes multiple threads crash simultaneously, e.g.:
[thread 202 also had an error]
Additional notes:
- Crashes occur during random runtime stages, including server startup and
plugin remapping.
- The JVM logs these segfaults but sometimes the server keeps running.
- Core dumps are disabled by default (ulimit -c).
- I can provide others hs_err_pid.log and replay_pid.log files if needed.
Please advise if this is a known issue or if there is a workaround for
Ubuntu’s OpenJDK 21 in this context.
Thanks in advance!
