分段违规导致 Artifactory 故障

大家好，我们又见面了啊~本文《分段违规导致 Artifactory 故障》的内容中将会涉及到等等。如果你正在学习Golang相关知识，欢迎关注我，以后会给大家带来更多Golang相关文章，希望我们能一起进步！下面就开始本文的正式内容~

我们在几个环境中运行 artifactory oss 7.4.3，所有环境都是 linux (rhel 7)。他们使用本地存储库来进行 maven 工件的标准下载/上传。其中两个环境在过去几周遇到了“分段违规”错误。我无法找到有关常规操作期间发生的此错误的任何文档。我的问题是我应该如何解决该错误？

panic: runtime error: invalid memory address or nil pointer dereference
[signal sigsegv: segmentation violation code=0x1 addr=0x18 pc=0x576a4f]

发生这种情况后，该服务将不可用，直到有人重新启动 artifactory。它显示在 console.log 文件中，但除了以下堆栈跟踪（在两个单独的实例中看起来几乎相同）之外，周围的日志记录似乎并不相关。

解决方案

这是由于当时使用的Go运行时（1.14.2）中的一个错误，更多详细信息请参阅https://groups.google.com/g/golang-announce/c/XZNfaiwgt2w/m/E6gHDs32AQAJ

从 Artifactory 7.7.0 开始已修复，因此您可以升级到最新版本（撰写此消息时为 7.10.6）
