Subject [jira] [Commented] (COUCHDB-1444) missing_named_view error on existing javascript design doc and view
Date Fri, 16 Mar 2012 20:23:39 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1444?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13231587#comment-13231587

Sam Lown commented on COUCHDB-1444:
-----------------------------------

Looking at the logs, and a bit before, it appears that the database *stopped* checkpointing
view updates for the Payment design. Changes were made to other documents, and other views
continued to update, but as soon as the Payments view was called no attempt to udpate the
view was made and 404 was returned. Maybe this is related. A few log examples:

65410 for maxi _design/Payment

404

I've not seen anything else related to the Payment design doc out of the ordinary.

>    Affects Versions: 1.1.1
>         Environment: Ubuntu 11.01 64 bit Erlang R13B03
>            Reporter: Sam Lown
>            Priority: Critical

> Moved over from issue: https://issues.apache.org/jira/browse/COUCHDB-1225 which has similar
symptoms but the view is written in Erlang.
> On our production server for no apparent reason, one of our views just suddenly stopped
responding to requests. The design document was still visible in Futon and the "all" view
did provide a list of documents. All other views in the ddoc responded with a 404 {"error":"not_found","reason":"missing_named_view"}.
> Restarting the couchdb server resolved the issue, and I've as yet been unable to reproduce
the problem.
> Here is the last successful log entry for the view:

> I could see nothing in the logs out of the ordinary.
> Obviously, this problem is very alarming indeed and not something I've come across before
in CouchDB. As you can see the view in question is related to Payments, which is something
we really do not want to go wrong. 
> Please let me know if I can provide more information.
