[GitHub] [rocketmq-client-go] dbl-x opened a new issue #527: [Master][v2.1.0-rc4][BUG] panic at internal.(*namesrvs). getNameServerAddress
dbl-x opened a new issue #527:
URL: https://github.com/apache/rocketmq-client-go/issues/527
**BUG REPORT**
**Please add the branch name [Native]/[Master] at the header of the Isssue title.**
1. Please describe the issue you observed:
- When concurrent UpdateNameServerAddress and getNameServerAddress, because namesrvs.srvs has changed, and namesrvs.index is not adjusted accordingly, the execution of "s.srvs[s.index]" causes the array to out of range
2. Please tell us about your environment:
- rocketmq-client-go: v2.1.0-rc4 and master
3. Other information (e.g. detailed explanation, logs, related issues, suggestions on how to fix, etc):
```
