> Key: ZOOKEEPER-3829
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3829
> Project: ZooKeeper
> Issue Type: Bug
> Components: server
> Affects Versions: 3.5.6
> Reporter: benwang li
> Priority: Major
> Attachments: d.log, screenshot-1.png
>
>
> It's easy to reproduce this bug.
> {code:java}
> //代码占位符
>
> Step 1. Deploy 3 nodes A,B,C with configuration A,B,C .
> Step 2. Deploy node ` D` with configuration `A,B,C,D` , cluster state is ok
> now.
> Step 3. Restart nodes A,B,C with configuration A,B,C,D, then the leader will
> be D, cluster hangs, but it can accept `mntr` command, other command like `ls
> /` will be blocked.
> Step 4. Restart nodes D, cluster state is back to normal now.
>
> {code}
>
> We have looked into the code of 3.5.6 version, and we found it may be the
> issue of `workerPool` .
> The `CommitProcessor` shutdown and make `workerPool` shutdown, but
> `workerPool` still exists. It will never work anymore, yet the cluster still
> thinks it's ok.
>
> I think the bug may still exist in master branch.
> We have tested it in our machines by reset the `workerPool` to null. If it's
> ok, please assign this issue to me, and then I'll create a PR.
