Crashpad folder grows to 50GB+ with no cleanup mechanism (macOS)

Environment

• OS: macOS
• Codex version: 0.139.0
• Location: ~/Library/Application Support/com.openai.codex/web/Crashpad

Problem

The Crashpad directory has grown to 50GB, consuming the entire disk and causing Codex to stop functioning (No space left on device).

The folder contains:

• attachments/
• completed/
• new/
• pending/
• settings.dat

Root Cause

Crashpad is designed to upload crash dumps to a remote server and then clean up. If no upload endpoint is configured or upload fails silently, dumps accumulate indefinitely with no size limit or TTL.

Impact

• Disk full → Codex crashes → more dumps → worse disk usage (death spiral)
• Codex CLI fails with: No space left on device (os error 28)
• No warning or notification to the user

Steps to Reproduce

1. Install Codex Desktop
2. Leave it running for several months
3. Check ~/Library/Application Support/com.openai.codex/web/Crashpad

Expected Behavior

Crashpad should either:

1. Upload dumps and delete them after successful upload, OR
2. Enforce a size/count limit (e.g. keep last 10 dumps), OR
3. Auto-clean dumps older than N days

Workaround

rm -rf ~/Library/"Application Support"/com.openai.codex/web/Crashpad
