几天前，我注意到我的工件实例不再运行。现在，我无法再次启动它。在/opt/jfrog/artifactory/tomcat/logs的localhost日志中，我找到了很长的堆栈跟踪记录，但是我不确定这是否是实际的问题，因为它似乎已经在一切正常的时候出现了。
2周后更新：最初编写此问题几天后，工件又突然运行。我不明白为什么，因为我尝试尝试的一切似乎都无济于事。现在，同样的问题又回来了……

我曾尝试删除derby文件夹中的.lck文件，因为以前这似乎已经解决了其他人的“ Another instance of Derby may have already booted the database /var/opt/jfrog/artifactory/data/derby”问题，但对我来说没有任何改变。在下一次启动工件之后，文件又恢复了，并且在日志文件中显示了相同的错误。
由于systemctl start artifactory.service的超时投诉我将START_TMO中的artifactory.default提高到300，但仍然存在相同的问题。我还根据this SO question的第一个答案在另一个文件中提出了START_TMO。
我不知道发生了什么，非常感谢您的帮助/建议。
