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

Thanks for the report, but there's not enough information here for us to investigate.
Are these processes launched by the agent or by the codex harness? I'm guessing from your description that it's the agent.
