Hello all,

Hosted a SolrCloud - 6 Nodes - 36 Shards x 3 Replica each -> 108 cores
across 6 servers. Moved in about 250M documents in this cluster. When I
restart this cluster - only the leaders per shard comes up live instantly
(within a minute) and all the replicas are shown as Recovering on the Cloud
screen and all 6 servers are doing some processing (consuming about 4 CPUs
at the back and doing a lot of Network IO too) In essence its not doing any
reads are writes to the index and I dont see any replication/catch up
activity going on too at the back, yet the RAM grows consuming all 96GB
available on each box. And all the Recovering replicas recover one by one in
about an hour or so. Why is it taking so long to boot up, and what is it
doing that is consuming so much CPU, RAM and Network IO? All disks are
reading at 100% on all servers during this boot up. Is there are setting I
might have missed that will help?  

FYI - The Zookeeper cluster is on the same 6 boxes.  Size of the Solr data
dir is about 150GB per server and each box has 96GB RAM.

Thanks,
Anand
