[jira] [Resolved] (COUCHDB-994) Crash after compacting large views

["Robert Newson (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/COUCHDB-994?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Newson resolved COUCHDB-994.
-----------------------------------

    Resolution: Fixed

I believe this is resolved. The couch_db:close(nil) path has been eliminated and we know write a header before flipping the view file, which largely mitigates the category of problem itself.

> The database has over 9 million records. Several of the views are relatively dense in that they emit a key for most documents. The views are successfully created initially but with relatively large sizes from 20 to 95G. When attempting to compact them, the server will crash upon completion of the compaction.
> This does not occur with the released 1.0.1 version but does with the 1.0.x svn version. I'll attach example logs. Unfortunately they are level error and may not have enough information.
