activemq内嵌到java程序，broker和Consumer所在程序直接kill,producer检测不到失连

Question

服务器端有多个进程，其中进程A中启动broker和consumer监听其他进程状态，进程B、C、D都有producer，会定时发报活信息，

B、C、D按顺序启动，这时候直接在任务管理器中kill进程A，进程B无法检测到connection断开，重启A后，B的报活消息始终收不到，将activemq外置，直接中bat起的话，一切正常，有谁知道是怎么回事？

Answer 1

上述描述问题B、C、D都是A的子进程！

现在发现问题在于，activemq所在的java进程如果启动子进程，该父进程重启后与之前的connection都失连，经定位，发现父进程关闭后，子进程中发生阻塞：
