> Currently, there is no way to control when a Solr node goes down.
> If the server is having high GC pauses or too many threads or is just getting too many queries due to some bad load-balancer, the cores in the machine keep on serving unless they exhaust the machine's resources and everything comes to a stall.
> Such a slow-dying core can affect other cores as well by taking huge time to serve their distributed queries.
> There should be a way to specify some threshold values beyond which the targeted core can its ill-health and proactively go down to recover.
> When the load improves, the core should come up automatically.
