What about reset by peer?

写了一个多币种的策略大约有7个币种，这个多币种的策略每5分钟每个币种大约获取一次record和ticker.并且有一个websocket连接每秒读取一次订单成交数据。

I started running at 22:30 last night, today at 6 am I reported an error, I have reported it before, the key is that after the error, the hard drive will stop working, what can I do?

Can I resolve this by judging whether each retrieval is null because it was not acquired to ticker resulting in the following statement null?Or is it because the server is too high in concurrency?
