Problem Description:
org.apache.rocketmq.client.exception.MQClientException: Send [3] times, still failed, cost [840]ms, Topic: top_1, BrokersSent: [a, a, a]
........
.......
Caused by: org.apache.rocketmq.client.exception.MQBrokerException: CODE: 1 DESC: create mapped file failed, server is busy or broken.
Each software version:
Operating system version: win10
JDK：1.8
MQ version: 4.3.0 (from the original 4.9.4/4.7.1 to 4.3.0 is still the problem)
Troubleshooting (:
I searched for various answers on the Internet, and the summary is as follows (it doesn’t work well for my problem):
1. Check whether the nameServer and broker are started successfully;
2. Check whether the connection information is configured correctly;
。。。。
My solution:
Check the jdk and find that it is 32-bit, change it to 64-bit and it will be OK
As a record of stepping on the pit, I hope it can help you.
