> Issue Type: Bug

> Priority: Major
> Attachments: zookeeper.log

> I have an app AA connect to zookeeper and register a temporary path such as /brokers/ids/10，and I have another app BB also connect to zookeeper. At some point, AA BB and ZooKeeper both restarted
> before restart:
> AA connect log in zk : [2021-03-07 08:47:43,468] INFO [SyncThread:0] Established session {color:#FF0000}0x10000053ef90000{color} with negotiated timeout 8000 for client /{color:#FF0000}22.20.0.45{color}:59966 (org.apache.zookeeper.server.ZooKeeperServer)
> after restart:
> BB connect log in zk:[2021-03-07 08:58:51,351] INFO [SyncThread:0] Established session {color:#FF0000}0x10000053ef90000{color} with negotiated timeout 30000 for client /{color:#FF0000}22.20.0.47{color}:39360 (org.apache.zookeeper.server.ZooKeeperServer)
>
> I understand that when ZooKeeper restarts, the transaction log and snapshot files will be loaded, and the old session({color:#FF0000}0x10000053EF90000{color}) and the temporary path will be loaded,If App BB gets the old session {color:#FF0000}0x10000053EF90000{color}, the session will not expire, the temporary path（/brokers/ids/10） will not be deleted, and App AA will not be able to re-register the temporary path(/brokers/ids/10)。
> That's my question，looking forward to your help. Thank you.
