caching - 清漆在过载时崩溃

问题描述

我正在使用 varnish v 4.1.1，在我们的系统中，一段时间后 varnish 突然崩溃并且 iowait 提高了很多，我们应该重新启动 varnish 以修复它。这是粉碎清漆后的journalctl resault：问题2：我决定安装新版本的清漆，哪个版本最好？varnish_6.3.1-1xenial_amd64.deb 或 varnish_6.0.5-1xenial_amd64.deb 感谢您的回答

解决方案

检查 dmesg 中的 OOM，如果你发现任何，那么你的系统内存不足，这是 Varnish 被杀死的原因。

还可以--human gives让您很好地了解可用内存。
