    [ https://issues.apache.org/jira/browse/COUCHDB-1441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13230531#comment-13230531 ] 

Dave Cottlehuber commented on COUCHDB-1441:
-------------------------------------------

should have added that this requires admin access to DB or server to do this, its not a DoS opportunity. More like "rm -rf may cause premature data & job loss".

> when creating a simple _rewrite loop, the db will start to eat cpu and take more & more memory
> for testing i created:
> {"_id":"_design/loopa","rewrites":[{"from":"","to":"../loopb/_rewrite"}]}
> {"_id":"_design/loopb","rewrites":[{"from":"","to":"../loopa/_rewrite"}]}
> accessing $dburi/_design/loopa/_rewrite/ will start the loop
