重启后 Varnish 无法启动

Question

我已经安装了 varnish 4.1.2，它可以从命令行正常启动，但重新启动服务器时无法启动。

系统日志显示该地址已被使用（端口 8080）。此服务器上没有安装任何其他东西，它是专用的 varnish 服务器。

从启动时看起来像是发生了恐慌，这是 varnishadm 中的 panic.show 的输出

使用 varnishd -C -f /etc/varnish/default.vcl 时VCL文件编译文件

看起来主进程仍在运行。终止所有 varnishd、varnishlog 和 varnishncsa 进程可让服务重新启动。
