ELK - Growing Pains with kibana, elastic search and logstash

We've had a variety of problems with this stack.  Here are some issues:
Redis dies on us.
Once Redis dies on us... our logstash-forwarders can't send msgs.
They seem to keep log file handles open and thus disk space isn't reclaimed when log rotation occurs.

Nice blog post of someone else's troubles:
