Originally created by @mchzimm on GitHub (Jul 9, 2025).

Originally assigned to: @thdxr on GitHub.

immediately after starting up (AKA "opencode" in Linux CLI, nothing else, no command issued) the app spawns "gopls" threads, each with increasing mem footprint, eventually crashing the OS, requires spamming CTRL-C ("/exit" won't fully quit the app).

so i started w/ v 0.2.6, because i remembered that one worked, then updated version-by-version. the "mem leak" issue starts with opencode v0.2.10, although it stabilizes after a few minutes and using up ~10gb, and cpu is going quite wild also:

this only got worse then going forward from v0.2.11 onward, and i had to spam CTRL-C to stop before it'd lock up the OS:

i upg to 0.2.18, the mem increase and high cpu util issues seem to be resolved.

still a lot of gopls but at with much less mem allocation and cpu utilization, and not keep spawning those repeatedly:

so far so good!
