Windows: Process explosion and severe memory leak on startup #32274
Description
Bug Report: Windows Client - Process Leak and High Memory Usage on Launch
Description
After installing or reinstalling OpenCode on Windows, launching the app spawns numerous extra processes. Memory usage rises rapidly, accompanied by high CPU load, and the program eventually freezes and becomes unresponsive.
I have tried all common fixes with no improvement:
- Reboot the computer
- Install and run the program as administrator
- Complete uninstall and full cleanup of all config and cache folders
- Re-download the installation package for a fresh install
Steps to Reproduce
- Download the latest OpenCode installer from official site
- Install with default settings
- Launch OpenCode
- Check Task Manager: multiple processes start up right away, memory keeps increasing, and the UI stops responding soon after
OpenCode version
Latest official release
Operating System
Windows 11 (64-bit)
Terminal
Default Windows environment, no custom terminal applied
Expected Behavior
The app launches with a normal number of processes and stable, reasonable memory usage, and keeps responsive during use.
Actual Behavior
Multiple redundant processes are created on startup. Memory and CPU usage keep climbing continuously, leading to program freeze. I have to force end the processes to close it.
Additional Context
This issue has the same symptoms as existing tracked problems #28680 and #20695 related to memory leak on Windows. I can provide logs or screenshots if required.
