我正在尝试使用Docker（1.9.1）的Varnish 4.1。 我使用musl-libc在Alpine Linux 3.2中构build了一个docker镜像，以减less镜像大小。
Dockerfile：
FROM alpine:3.2 RUN echo 'http://dl-4.alpinelinux.org/alpine/v3.3/main' >> /etc/apk/repositories && \ apk update && apk upgrade -U -a && \ apk add --update varnish \ && rm -rf /var/cache/apk/* Add Comment 当我尝试在容器内部运行时，有时会出现段错误，但有时候我不会：

有时候我会连续得到2-3段断层，第三，第四次成功运行。

另外，当我运行它成功，并尝试清除caching（禁止），subprocess退出与段错误。
这是由musl-libc引起的吗？
进入完全相同的问题。 似乎来自高山的形象。 切换到Ubuntu，它工作正常。
