和大目老师通过QQ群沟通，最后大目老师拉取代码库到本机分析，找到了原因；
问题解决思路：
1、报错：
The web application [ROOT] appears to have started a thread named [com.alibaba.nacos.naming.failover] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:
检查机器内存，发现服务器内存足够；
2、检查springboot、springcloud-alibaba、springcloud三者版本，是否存在冲突；
三者版本分别为：2.2.1.RELEASE、2.2.1.RELEASE、Hoxton.SR6；
关键报错信息：
The following method did not exist:
org.springframework.messaging.converter.AbstractMessageConverter.<init>([Lorg/springframework/util/MimeType;)V
经过debug发现：spring-messaging 2.2.1版本 AbstractMessageConverter有个构造方法不存在，导致报错
springboot版本升级到2.2.2及以上后解决
