["haiyang1985 (GitHub)" <gi...@apache.org>]

- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
- [ ] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate.

### Environment

* Dubbo version: 2.7.3 & 2.5.10
* Operating System version: mac
* Java version: JDk 1.8

### Steps to reproduce this issue

1. DubboSaveRegistryCache thread cost a lot of cpu when device is full. 
```
 [DUBBO] Failed to save registry store file, cause: No space left on device, dubbo version: 2.0.1, current host: 10.14.129.133
java.io.IOException: No space left on device

	at java.lang.Thread.run(Thread.java:748)
```
2. when device is full, it will retry doSaveProperties and log warn in infinite loop.

Pls. provide [GitHub address] to reproduce this issue.

### Expected Result
Seems the version check is not takes effect, doSaveProperties should be stopped.

### Actual Result
retry doSaveProperties when device is full takes a lot of cpu time.
