###遇到的坑,错误信息

1.RocketMq Exception "connect to <：10909> failed,{rocket使用10911和10909端口,有时候是报10911的错误,}

如果出现这个错误,有两种可能,一种是端口未开放 :(一般情况下看下先看下端口开放情况)

producer.setVipChannelEnabled(false);

consumer.setVipChannelEnabled(false);

如果仍没有解决,修改broker.conf,添加注释掉的那两行.

 

2.Out of Memory Error 

查看启动文件配置的jvm参数,修改一下就好了,具体文件上面已经提出
