我之前发过这里关于我遇到的一个错误；显然那不是发布的正确地方。
希望这是，我不知道把它放在哪里。
回顾一下，我在 Ubuntu 上运行 Minecraft 服务器，使用参数-Xms1024M -Xmx10G Minecraft_Server_1.20.jar nogui，我不明白是什么导致了崩溃。它因 SIGSEGV 错误而崩溃，可能是由 libjvm 中的某些东西引起的，但我不明白如何正确诊断问题
截至目前，
- 我尝试按照另一位用户的建议更新到 JDK 18，但仍然崩溃。
- 我尝试重新安装 JDK 和服务器，问题仍然存在
- 我已经进行了内存测试，内存故障不是问题
如果这是 JDK 中的一个错误，您能否告诉我如何报告它或分析这个问题？另外，我尝试读取“核心转储”，但找不到该文件，据说该文件位于/opt/minecraft/minecraftserver/antServer/core.551710，但没有以 core 开头的文件？如果您能帮助我理解这两个问题，我将不胜感激。
