What happened

我们用mysql替代zk作为注册中心。替换后有6台master，其中一台master的jvm超过，基本每秒都会发生GC，同时在不停的创建新对象。排查下来后发现 如图的AbandonedConnectionCleanupThread持有的map过多

What happened

We use mysql instead of zk as the registration center. After the replacement, there are 6 masters, and the jvm of one master exceeds the limit. GC will occur basically every second, and new objects will be created continuously. After troubleshooting, I found that the AbandonedConnectionCleanupThread in the picture holds too many maps.

You can consider to increase the spring.datasource.hikari.idle-timeout value and observe again to see if there is still the same problem

@nikusu417 Full GC always on 1 of the 6 masters or randomly ? Full GC 是始终发生在其中某台master还是随机出现在各台master上?
