Subject Overseer session expires on multiple collection creation
Date Fri, 21 Apr 2017 13:04:49 GMT
Hi, 
I am trying to create multiple collections with 2 shards and 2 replications
each.
After 5-6 successful 
overseer status response for 5 creations shows 40k requests for
collection_operations=>am_i_leader which is a bit odd. 
and I get 
Am I not supposed to create 8-10 collections one after the other or is there
some configuration that I'm missing.
On creation of 8th collection I get following overseer session expired
exception 

nExpiredException: KeeperErrorCode = Session expired for
/overseer/collection-queue-work/qnr-0000000024
