System slow, ram and cpu getting hammered?

Tell codex....

“Check for any old background processes you started that are still running. Close them. From now on, always close any process you start once the task is finished.”

codex is launching python processes and never shutting them down until I asked it to. Even restarting VS code wont help until what codex started is shut down. The issue never came back

vs code + codex + win 10

extent analysis

TL;DR

Closing unnecessary background processes launched by Codex can help alleviate system slowdowns and high resource usage.

Guidance

  • Identify and close any unnecessary background processes started by Codex to free up system resources.
  • Develop a habit of closing processes once their tasks are completed to prevent similar issues in the future.
  • Consider implementing a mechanism to automatically terminate processes after a certain period of inactivity or when their tasks are finished.

Example

No specific code snippet is provided as the issue is more related to process management rather than code implementation.

Notes

The issue seems to be specific to the interaction between Codex, VS Code, and Windows 10, so the solution might not apply to other environments or operating systems.

Recommendation

Apply workaround: Closing unnecessary background processes and developing a habit of managing them properly can help mitigate the issue, as it has already shown to resolve the problem in the past.
