Christopher Bonhage commented on COUCHDB-1651:
----------------------------------------------

Paul, I think you'll find the issue completely resolved with my patch above. The '1651-recursive-rewrite-leak' branch solves the symptom of the error being unrecoverable, but does not address the root cause of the error, which is that re-used processes are being treated as recursed rewrites.

> Problem:
> The requests work as expected for some unknown period, then begin to respond with a 400 status and the "Exceeded rewrite recursion limit" error message. Changing the rewrites rules for both applications, including setting them to empty arrays, had no effect.
> The problem was solved by restarting the CouchDB service.
