> The problem we saw was that when the solr overseer leader experienced temporary zk connectivity
problems it stopped processing overseer queue events.
> This first happened when quorum within the external zk ensemble was lost due to too many
zookeepers being stopped (similar to SOLR-5199). The second time it happened when there was
a sufficient number of zookeepers but they were holding zookeeper leadership elections and
thus refused connections (the elections were taking several seconds, we were using the default
zookeeper.cnxTimeout=5s value and it was hit for one ensemble member).
