Ontotext GraphDB 进程终止

Ontotext GraphDB process terminates

我在 Ubuntu 服务器上安装了 graphDB 8.0.2 运行ning。 我运行它与/var/lib/graphdb/bin/graphdb -Xmx1224M -Xms712M &。 graphdb 进程无故停止。我在日志中没有看到任何错误(见下文)。 这可能是什么原因? 我该如何调试呢? 我已经增加了分配给进程的内存,但仍在试验这种行为。更多的内存会解决任何问题吗?

感谢您的帮助

根据日志,我唯一想到的是某些东西向 GraphDB 发送了中断信号并且它正在正常退出。

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