I’ve been having this happen with a client for the last few deliveries of software and all it’s derivatives…
“Works on my machine.”
“Works in DEV.”
“Looks fine over here.”
But it doesn’t, it never did, the problem was always there. Maybe your machine had the right CPU to get past that race condition or maybe that day when you did your test that spike in memory usage wasn’t your youtube video but your app itself.
Works on My Machine is a challenge to figure out what went wrong with your code and not be satisfied with a Gremlin lurking out there, waiting to come out once you deploy your code.
Don’t give it a spot to rest and think.
