Subject [jira] [Commented] (COUCHDB-1651) Server responds 400 "Exceeded rewrite recursion limit" indefinitely
Date Fri, 15 Feb 2013 21:33:13 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13579521#comment-13579521

ASF subversion and git services commented on COUCHDB-1651:
----------------------------------------------------------

Commit 8199c5d86c5548659e14e342b659dd233ad65096 in branch refs/heads/1651-recursive-rewrite-leak
from [~rnewson]
[ https://git-wip-us.apache.org/repos/asf?p=couchdb.git;h=8199c5d ]

Terminate process that exceeds rewrite limit

A process that exceeds rewrite limit returns a 400 error to the client
but can then be used for further requests, which also return 400
incorrectly.

This patch ensures the request process dies, taking its process
dictionary with it.

> 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.
