@codezm 首先感谢您的BUG反馈, 我是无情的自动回复机器人，请您快速确认以下几点来帮助我们定位您的问题：

  1. 如你是手动升级编译的而不是首次编译, 确保你在编译前运行make clean清理了上次编译的内容

  2. 如你使用的是Linux系统, 使用以下命令运行你的程序, 以能够复现BUG的方式操作你的程序, 并在程序运行一定时间后, 将位于/tmp目录的valgrind.log日志内容贴在此issue中

USE_ZEND_ALLOC=0 valgrind --log-file=/tmp/valgrind.log php xxx.php

  1. 如你使用的是macOS系统，将无法使用valgrind, 请提供能够复现问题BUG的PHP代码

  2. 若以上需求都无法满足，请您在此表明, 我们将快速接入人工处理

请问如何关闭 Tracker 扩展? 是编译参数 --enable-trace-log 吗？

php --ini找到你加载的swoole_tracker扩展，注释掉就行了
