Hey Edward, Error 121 often indicates an out-of-memory condition occurring for your app's instance. This would result in the instances crashing once they reach the memory limit and needing to spin up new instances, leading to request-handling latencies. Is it possible you could do a quick profiling of your memory usage? The method will vary depending on the programming language.
