Subject [jira] [Commented] (COUCHDB-1163) Document returned by id, but cannot be found by rev
Date Tue, 17 May 2011 14:16:47 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13034777#comment-13034777

Clare Walsh commented on COUCHDB-1163:
--------------------------------------

Adam,

Thanks for the info :)
Yes, we were running 1.0.1 when this all started... then upgraded to 1.0.2 partway through
apparently, in an attempt to make the horror stop. But in order to try to replicate/debug
the problem while cleaning up our original system we copied the db file and mounted it to
various dev environments. I'm running trunk svn from Friday, James is running 1.0.2
Any other information you need? Any fix I can try? Or logging I can put in to help more?

Thanks 
Clare

> Somehow, our cluster has developed the following problem on a handful of documents. Will
post reproduction steps if we find them. All properties have been redacted. All the documents
this affects also have attachments, if that is significant. Once a document is in this situation,
it causes conflict detection, replication and include_docs to behave incorrectly or outright
fail.
