OpenAI Codex Desktop suffers from severe process leak on Windows

By PulseAugur Editorial · [1 sources] ·

A user on Reddit reported a significant performance issue with OpenAI's Codex Desktop application on Windows. The application appears to suffer from a process leak, leading to hundreds of background processes accumulating over time. This results in extremely high CPU usage and a drastic reduction in available RAM, making the system nearly unusable. The user found that manually terminating these duplicate processes temporarily resolves the issue, suggesting a bug in how the application manages the lifecycle of its helper processes and tool servers.
