High Memory Usage: firing off many https requests in Task.async calls has huge memory impact

[sdr]

This post looks similar and is caused by ssl certs. Not sure if your issue is the same but it’s worth looking into.

Ssl_gen_statem:init/1 process takes high memory during periods of higher throughput

Essentially I see multiple attempted requests to DynamoDB which hit a 20 second timeout and error out. During this period there is a spike in response time for Dynamo requests and the ssl_gen_statem processes jump to the top of the observer. Other calls made to DynamoDB also increase, for instance a put statement which is usually 200ms goes to 30 seconds. Eventually the node is disconnected from the cluster. Also DynamoDB is my only upstream service and the process state for the ssl_gen_statem…
