+description: 本文描述了 Kuboard 的一些已知问题
+---
+
+# 已知问题
+
+## SSE4.2 compatible
+
+Kuboard 自 v1.0.7 开始，使用 [OpenResty](https://hub.docker.com/r/openresty/openresty) 提供的基础镜像，该镜像存在的一个问题是：CPU 必须兼容 SSE4.2。这意味着，一部分 2007 年以前的 CPU 可能无法兼容。请参考 [https://github.com/openresty/docker-openresty/issues/39](https://github.com/openresty/docker-openresty/issues/39)
+
+出现此问题时，通过 kubectl 命令查看 Kuboard 日志
+``` sh
+kubectl logs -f -l k8s.eip.work/name=kuboard -n kube-system
+```
+
+
+错误提示如下所示：
+```
+Illegal instruction     (core dumped) nginx -g "daemon off;"
+```
