I test this patch on our product cluster, with five machine, each with 6
workers as max;
The topology based on trident run about 5 hours without fails.
Then I kill one worker called A, then I found the log below on worker
B.Worker B don't exit as worker A died.

As worker A died, nimbus reschedule a new worker F, then worker B connect
to worker F.

```
worker B connect to worker F successful before worker B close connection
with Worker A.
Because this is our product cluster, I rewrite the hostname and ip in the
log.
