------------------------------------------------------------
External Zookeeper is 3.8.0 with three nodes and NiFi 1.16.1. I've been unable
to reproduce this outside of AWS but it happens pretty consistently when NiFi
is under a load.
I'm still pretty sure it's being caused by AWS's firewall(security groups)
severing connections between EC2s but local attempts to reproduce using
firewalld and on linux hasn't reproduced it.

> After a loss of connection to Zookeeper a NiFi node never successfully

> no Cluster Coordinator and a Session timeout has elapsed while SUSPENDED
> repeatedly until you restart NiFi.
> The error described is the same one at

> in NiFi for several versions now.
> NiFi version is 1.15.3 and Zookeeper 3.6.3
