yeah same, it is asking for that much access, i cant use the unlimt command in linux, and i suspect memory leak too. i have to close the opencode completely after some hour and restart it otherwise it would get hang

Can anyone share a session causing this?

opencode export > session.json

You can dm privately too

I can't replicate this

Same issue. Opencode consumed 15Gb Memory in one instance. With multiple parallel instances, ended up crashing my Xserver (Ubuntu 24.04) with 128Gb memory

Common pattern across all sessions:

2-3 opencode instances per git repo
Average 2-3 compactions per session
All running parallel

Same issue. Mac using Sequoia 15.7.2. node balloons to >70GB within 30 seconds... suspect it is b/c one of the sub-folders w/in the folder I start in has many large files, so my bad 😓
