go - Imaginary 在高负载时感到恐慌

问题描述

我在 docker 中运行了imaginary，这是一个基于 的图像处理工具libvips，并通过wrk如下方式进行了一些工作：

 wrk --latency -s print.lua -c 30 -t 1 -d 60m 'http://127.0.0.1:9000/crop?width=1440&height=1440&stripmeta=true&quality=70&type=jpeg&file=1M.jpg'

一段时间后它像这样崩溃

fatal error: unexpected signal during runtime execution

这是恐慌日志的长版本：github问题

我搜索了很多，但没有任何帮助。我应该从哪里开始解决这个问题？非常感谢你
