> We just ran into a production incident with TCP SYN storms on port 2181
> (zookeeper).
> In our case the slave cluster was not running. When we bounced the primary
> cluster we saw an "unbounded" number of failover threads all hammering the
> hosts on the slave ZK machines (which did not run ZK at the time)... Causing
> overall degradation of network performance between datacenters.
> Looking at the code we noticed that the thread pool handling of the Failover
> workers was probably unintended.
> Patch coming soon.
