我在 Ubuntu 服务器上运行了 graphDB 8.0.2。我用/var/lib/graphdb/bin/graphdb -Xmx1224M -Xms712M &. graphdb 进程无缘无故停止。我在日志中看不到任何错误（见下文）。这可能是什么原因？我该如何调试呢？我已经增加了给进程的内存，但仍在试验这种行为。更多的内存会解决什么问题吗？

谢谢您的帮助

根据日志，唯一想到的是将中断信号发送到 GraphDB 并且它正在优雅地退出。

在后台运行 GraphDB 的推荐方法是添加 -d （守护进程）选项，例如在您的情况下/var/lib/graphdb/bin/graphdb -Xmx1224M -Xms712M -d。
