I have installed Redis to AWS (t3.nano instance) from Redis launchpad. It has now been running for a couple of weeks and is in a very low usage, just a few hundred requests per day.
Today was the second time I noticed that Redis was not responsding to requests. Connection to the server works, but it doesn't respond to PING and CPU usage (checked via ec2 monitoring) is 100 %.
I'm using bitnami-redis-5.0.5-2-linux-debian-9-x86_64-hvm-ebs-nami (ami-0e13031eaf1288c23).
In the configuration file I have removed password and protected mode.
Any ideas what to do?
