Codex Desktop on macOS is continuously generating Crashpad pending dump files without bounds, causing rapid local disk growth. The issue involves paired `.dmp` and `_sidecar.json` files accumulating in `~/Library/Application Support/com.openai.codex/web/Crashpad/pending`. In one day, this directory reached 4.9GB with 54,504 files, growing at a rate of at least 5GB per day.
Despite the dump generation, the Codex app remains fully functional — users can interact with GitHub and inspect the filesystem normally. Evidence shows two `browser_crashpad_handler` processes running since May 30, 2026, under PPID=1, using the same Crashpad database with annotations `prod=Codex_Mac` and `ver=148.0.7778.179`. The problem appears to be active, unbounded dump generation rather than stale leftovers, as file counts increased during investigation.
No upload, processing, or rotation mechanism seems to be in place. The user has not shared minidumps publicly due to potential private data but can provide them via a secure path if OpenAI maintainers request. Expected behavior is bounded, processed, or rotated crash reports; actual behavior is uncontrolled accumulation consuming multiple gigabytes of disk space.
