runzhiwang updated RATIS-845:
-----------------------------
Description:
*What's the problem ? *
As the image shows, there are 245 instances of RaftServerImpl, but the map in
RaftServerProxy has only 16 entries. Because all the RaftServerImpl will be
put into the map in RaftServerProxy. So 229 instances of RaftServerImpl happen
memory leak.

*What's the reason ?*
When call
[RaftServerProxy::remove|https://github.com/apache/incubator-ratis/blob/master/ratis-server/src/main/java/org/apache/ratis/server/impl/RaftServerProxy.java#L94],
it did not call
[RaftServerImp:shutdown:|https://github.com/apache/incubator-ratis/blob/master/ratis-server/src/main/java/org/apache/ratis/server/impl/RaftServerImpl.java#L247].
