Description:
We faced some EBS issue on one of the multi level replication slave.Due to this mysql went for defunct mode.

when EBS got recovered , we observed it skipped 16 min binary logs.

And it  continue with skipped binary log position.

it skipped around  16 min data.

As per the replication topology it should start when slave stopped.But it skipped and continue with skipped binary log position .

can you please confirm why it behave like this?

How to repeat:
1. create muti level replication setup 1-> 2- > 3,
 2.create some EBS issue on mysql datadir on slave 2 .
3. Mysql will went for defunct mode.
4. check the mysql binary position.
