Codex rollout is generating an absurd number of session files
- The post complains that OpenAI Codex is creating a huge amount of rollout session files, to the point that the author calls it “insane.”
- The screenshot shows a disk-usage view with a /.codex/sessions/2026 folder consuming 360.6 GB, suggesting the agent is producing or retaining far too much session data.
- The author says no other coding agent does this, framing it as a standout product quirk or bug rather than a normal workflow issue.
