刚接触这个框架，代码都是之前同事写的，若是要解决这个问题的话，可以从哪方便解决

把Events.php 里上面加上declare(ticks=1);，然后reload。下次发生process_timeout时一般会打印更详细的调用栈，就能知道业务代码是在哪一行执行的慢

另外发生这种情况的时候一般会出现长时间busy的进程，通过手册这个方法也大概能定位到

好的，谢谢！

你好，服务现在已经运行了有大半年，代码修复需要段时间，有没有什么方法可以暂时解决这个问题？

业务处理慢只能业务想办法。看到是insert比较慢，可能是onMessage里批量循环插入了太多的数据导致耗时很高，也可能是mysql死锁或者高负载导致insert很慢

怎么查看是不是由于数据库慢导致的？

@1:busy进程显示了一下就消失了，无法用命令定位具体错误，请问还有其他办法嘛？

短暂的busy是属于正常现象，不用处理
