That was/is the original intent. ZK was built to "fail fast" when it
didn't know how to handle a particular case, or that case might be error
prone to handle. The expectation is that the parent will restart the ZK
server process when it fails.

Hi Andor,
I am using ZooKeeper release 3.4.10.
I checked the code, if follower fails to read from leader (e.g., read
timeout), it will close the socket, see
https://github.com/apache/zookeeper/blob/release-3.4.10/src/java/main/org/apache/zookeeper/server/quorum/Follower.java#L91:L85
for
details.
Hi Qian,
Which version of ZooKeeper are you using?
Would you please share the config files and leader logs too?
Also looks like you're trying to connect with an older client:
>>> Connection request from old client /10.249.255.10:42306; will be
dropped if server is in r-o mode
Andor
On Wed, May
Anyone has any ideas?

Hi,
I have a ZooKeeper cluster which has 5 nodes. Today the leader cannot be
connected due to a hardware issue, and then I found the 4 followers just
shutdown, here is the logs:
