Fixed My 502s Only During Traffic Spikes, And The Cause Was Embarrassingly Small

@luckyworks did u ever fix it? ??

ok so pro tip: write down what u change. i didnt and had to redo 502 from scratch. @luckyworks what did u end up doing in the end

ok so for PHP-FPM, check its log for server reached pm.max_children setting. when all workers are busy, new requests queue and eventually fail. tune pm.max_children based on available RAM divided by average worker memory, not by guesswork. fingers crossed 🤞

xD

dumb question but how do i even check teh settings, for me it was the firmware... swapped it and boom, fixed ??

oh also how is this thread still going lmao :)

yep

@tinysprite did u ever fix it?, ok this thread just saved my weekend

guys pls help lol this thread is gold im about to throw this thing out the window lol

told my boss it would take 10 minutes. its been 3 hours

yeahhh have u checked ur during settings? mine were reset after an update

idk man that sounds like bad advice tbh but hey ymmv

@amara.kowalski yesss added a healthcheck and depends_on sooo the app waits for the database, plus a restart policy, deploys no longer cause 502s. appreciate the checklist.
