Yonik Seeley commented on SOLR-3939:
------------------------------------

bq. Isn't that what capturing the starting versions is all about?

For a node starting up, yeah.  For a leader syncing to someone else - I don't 
think it should matter.

bq. but if you want to peer sync from the leader to a replica that is coming 
back up, if updates are coming in, you are going to force a replication anyway. 

If updates were coming in fast enough during the "bounce"... I guess so.

> When a leader core is unloaded using the core admin api, the followers in the 
> shard go into recovery but do not come out. Leader election doesn't take 
> place and the shard goes down.
> This effects the ability to move a micro-shard from one Solr instance to 
> another Solr instance.
> The problem does not occur 100% of the time but a large % of the time. 
> To setup a test, startup Solr Cloud with a single shard. Add cores to that 
> shard as replicas using core admin. Then unload the leader core using core 
> admin.
