i have 2 sevices like new has nothing just create a new sveltekit project and new hono project
Sveltekit is Using node-adpater
Hono is binary build using Bun
memory is Insanly high
On a Side note not sure if that mater im using Moonrepo which is a monorepo that Does optimized docker image well copying packages and stuff but highly dought it has anything to do with Bun or Node
i can link docker if that useful
im using Latest in both Node 24.6.0 and Bun 1.2.20

Let me Clarify something the apps are super simple, sure maybe docker build is incorrect but i dont understand what do u mean with WebP , im talking about Docker images not images plus even if docker image is large it should large in file size not like memory usage.
Plus i don't want to sound rude but it feels like ai response
5. TypeScript build issues - If using TypeScript, you might have:
Redundant builds from sharing types between backend and frontend
Duplicate build processes
im suing bun for hono which build an optmized binary anyway

Is the memory spike at a certain interval of code execution, during a particular function being executed, or is the pattern randomly distributed?
Can you provide the metrics graph's snippets of the past 7 days for both services (select a deployed service on Railway, & then go to the Metrics section)? This will allow us to show which service is consuming the memory.

according to the 'Public network traffic' graph it seems like there was ingress traffic happening at the same time the mem spiked

Is the memory footprint similar if this is running locally?

are you in contact with Connor from bun? have you provided them an MRE?
I Hope i don't go bankrupt before the fix because im using bun s3 client will be hard for me to remove it now

Ah so you can't just switch back to Node to check if the memory leak is bun specific.

Though, if it makes the situation better, at least memory leaks aren't Railway specific! 🙂
I’m not 100 % sure, but there was a moment when every JS service suddenly ballooned in memory and then—almost in unison—dropped back down. The spike was only about 10 %, so it was pretty minor, but I figured it might have been triggered by an update on your end. Either way, Railway’s been rock-solid for me—smooth sailing all around.

Memory usage is not dependent on our systems, the memory usage is solely your application's usage.
Anyway, I’ll be off having a long, heartfelt chat with my wallet until Bun sorts out that weird memory issue.
@Brody sorry to bother but why when i set limit 1gb memory dropped like that

Memory dropping after a re-deploy would be completely normal.
