   This issue might be a duplicate of existing issues. Please check:

   • Massive memory use on opening opencode when there is a very large file #2585: Very similar memory consumption issue where opencode used 29GB of RAM when processing large files. The root cause was identified as opencode loading a very large folder (.chunkhound with 27GB). Deleting large unnecessary files/folders solved the problem.

   Feel free to ignore if none of these address your specific case.

   Debugging suggestion: Check if your project directory contains any unusually large files or folders that opencode might be trying to process. You can share more details about your project structure or the /share results to help identify the root cause.

   wtf? This is on a very compact repository BTW, so there are probably some memory leaks somewhere in the codebase

   

   UPD: Nevermind this was not on a small repo, it was on a medium-sized repo
