My system sends the data to Redis via web server and ultimately stacks it in Elasticsearch. The thing is that Redis connection timeout error occurs when the traffic is small. The error always occurs at 5 AM in Korean time around one to five minutes. The memory usage rate of the Redis server rapidly increases at 5 AM, but still it’s only about 2GB. Currently I’m using the Redis premium price tier for your reference. BTW, I believe that my process doesn’t include any scheduler that can cause the rapid increase of the memory usage rate at 5 AM. Is there any chance that the error came from the Redis or Elasticsearch? I don’t see any problematic log around the error occurred time in the Elasticsearch. I look forward to your help.
