SQS Daemon by AWS

NodeJS workers in AWS EBS

SQS Daemon by AWS

1. nginx sits between sqsd and workers for no good reason!

   • Its presence creates more issues:

     • 5xx errors that claim "loss of connection to upstream server"

     • connection errors like ECONNRESET and various other socket hangup problems

2. sqsd itself is quite buggy too

   • messages end up on dead letter queue (DLQ) despite the worker reporting 200 OK for success.
