JiangHua Zhu commented on RATIS-2261:
-------------------------------------
I found at least 2 related issues.
1. When s0 starts ahead of schedule and becomes the Leader role. After starting
s3 and s4 subsequently, s0 will gradually become a follower, because s3 or s4
itself carries a higher term and sends appendEntries to s0.
Here are some logs:

2. When the client sends the setConfiguration() command, it cannot establish a
connection with s0. Here are some timeout logs.
