最初运行时还出现了个：core dump

看报错感觉是pcre扩展出现了内存问题，你关闭pcre扩展试试？

https://www.php.net/manual/zh/pcre.installation.php

PCRE 是 PHP 核心扩展，所以总是启用的

这个方案不太可行吧，而且项目依赖正则，关了就运行不起来了。

能否提供一个github仓库，我可以下载项目，然后调试复现出你这个问题？

在容器里错误变成里corrupted size vs. prev_size

https://github.com/NHZEX/yasd-tests

sudo docker build -t imi_test:yasd .

sudo docker run -it --rm \
 -p 9988:9988 \
 -e IMI_DEBUG=true \
 -e MAIN_DB_HOST=192.168.1.166 \

 -e MAIN_DB_USERNAME=db \
 -e MAIN_DB_PASSWORD=password \
 -e DEBUG_HOST=192.168.138.124 \
 imi_test:yasd

请求多几次，不是每次都出现的。 Get: http://192.168.138.122:9988/api

之前还有个项目是corrupted size vs. prev_size和double free or corruption (!prev)交替发生

可以考虑使用 swoole-src的 xdebug分支，https://github.com/swoole/swoole-src/tree/support-xdebug 可以直接使用xdebug进行调试，前提是PHP版本要大于等于8.1
