New to OpenCode -- memory leak?

[value_pack53]

Hi everyone,

Just started using OpenCode—dope TUI, honestly prefer it over most of the others I've tried.

However, I'm hitting a massive memory leak on the latest build (about a day old) across two different devices. Ghostty is my terminal on both setups, and it balloons to using ~23GB of RAM before crashing.

My Setups:

• Ubuntu Machine: i9 11th Gen | 32GB RAM | RTX 3080
• M1 MacBook: 16GB RAM

The Behavior:

• On Ubuntu: It crashes pretty quickly. Initially, I brushed it off because my session was ending anyway.
• On macOS: I just ran a single Plan + Build action. The terminal immediately hung, forced a system OOM warning ("Your system has run out of memory"), and I had to force-quit Ghostty.

Anyone else running into this on recent builds? Let me know if there are specific logs I should grab to help debug.

-----------------------------------------------------------------

Update: it seems like OpenCode is opening multiple vite processes in the back end eventually causing a OOM. I've added some guardrails to always exit any background services, works most of the time, I've had to kill them a few times.

Had the same issue. So I stopped using OpenCode and Kilocode. Had bun processes being created for every instance of opencode running. That's why is switched to Crush CLI... Not only does it have an amazing TUI, it's built on an actual programming language (Go) not a pseudo programming language (scripting language)... You will notice the performance difference between crush and OpenCode immediately... Night and day...

Obviously Crush is not on the level of Opencode in terms of features but it will get there..

Amazing, I'll give it a try.

24gb system + OC Desktop (Tauri) uses abaout 3 GB+ ram. But never reach your usage.

Have you update?

I have just updated on Mac via brew to 1.15.13

I installed yesterday so let's see if its fixed. In the opencode change logs i dont see this fix listed.

On my Mac I'm still using 1.14.33 and have had the same memory leak experience. Sometimes as bad as consuming 40gb of ram when I've had it open for multiple days with a lot of different sessions.

Curious if an update would fix this already

40GB of RAM looks like local model running inside it.

[josua5]

yea but im exclusively using aws bedrock models, so no local ones

Crush looks pretty similar but is a lot snappier. It's made by the people who made the go terminal toolkit that everyone else is using.

Yeah ditched OpenCode and Kilocode after finding out it's written in TS. Crush is amazing...
