英文:
cannot allocate memory error
问题
我刚刚将我的应用程序从Python迁移到Go，所以对Go还有点陌生。看起来我遇到了内存问题。在Ubuntu机器上通过supervisor运行时出现了getAudioOnlyInfo: fork/exec /usr/local/bin/youtube-dl: cannot allocate memory的错误。
编辑：
通过设置sysctl -w vm.swappiness=1解决了这个问题。
英文:
I just ported my app over from python so I'm a bit new to Go. It seems I am having a memory issues. getAudioOnlyInfo: fork/exec /usr/local/bin/youtube-dl: cannot allocate memory.
This is run on a ubuntu machine. Via supervisor.
Edit:
setting the sysctl -w vm.swappiness=1 resolve the issue

对于遇到这个问题的其他人，这是一个相关的最近问题在golang问题中
