HTTP 507 — Insufficient Storage
5xx Server Error
What it means
The server cannot store the representation needed to complete the request.
What to do about it
Check disk space. A full disk also causes surprising 500s elsewhere, since logs and temp files stop writing.
Where it sits
507 belongs to the 5xx family: The server failed to fulfil an apparently valid request. The fix is on the server side.
