ios游戏运行一段时间，几率poco server挂掉

:bulb:**相关项目:** Poco

**标题:** [BUG提交]ios游戏运行一段时间，几率poco server挂掉

**AirtestIDE版本:** 无

- [x] **使用了本地Pyhton环境运行脚本**
- Python版本: python3.8.8
- Airtest版本: v1.2.0

**报错描述:**
    iOS unity 游戏运行一段时间(可能10分，也可能1个小时以上)，几率poco server挂掉，报错就是simplerpc.py中拉取信息的语句报错。在不关游戏的前提下，此时poco永远连不上了。重启游戏后又正常了。

**相关截图:**
无

iOS会出现以上报错，我们把msg保存下来，发现msg是不完整的(没传完)。另外出现这个问题后，游戏不动，拿着iphone连AirtestIDE，是连不上的，报错

综上，可以判断游戏内poco的Server坏掉了，重启游戏后正常。安卓就没有

也出现过报错信息是如下的，感觉和上面的报错差不多，应该都是一个问题导致
