Running Redis 3.2.3 and LS 5.6.15. My setup is LS\>Redis\>LS\>ES. Everything in my stack is now 5.6.15. After the (package manager) upgrade I'm no longer getting events from Redis. So Far, I've re-installed the input and output plugins in Redis but not on LS. In my Redis box, I get the error below which I think means there is no input on the LS side to ingest but it was working before, not sure if I'm missing a step after the LS upgrade.

[2019-03-05T09:19:59,663][WARN][logstash.outputs.redis] Redis key size has hit a congestion threshold 2200000 suspending output for 1 seconds
