Ontotext GraphDB进程终止

Question

我在Ubuntu服务器上运行了graphDB 8.0.2。我和/var/lib/graphdb/bin/graphdb -Xmx1224M -Xms712M &一起运行它。graphdb进程无缘无故地停止。我在日志中没有看到任何错误(见下面)。这是什么原因？我如何调试这个？我已经增加了给进程的内存，但是仍然在实验这种行为。更多的记忆能解决任何问题吗？

谢谢你的帮助

基于日志，想到的唯一事情就是将中断信号发送给GraphDB，然后它就优雅地退出了。

在后台运行GraphDB的推荐方法是添加-d (daemonize)选项，例如在/var/lib/graphdb/bin/graphdb -Xmx1224M -Xms712M -d中。
