Couch crash after View compaction, unresponsive for 1-2 mins, view reindexes from scratch
-----------------------------------------------------------------------------------------

                 Key: COUCHDB-1224
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1224
             Project: CouchDB
          Issue Type: Bug
          Components: Database Core
    Affects Versions: 1.0.2
         Environment: CentOS 5.6 Server, on XFS raid1 array. Running as user couchdb. Build
was 1.0.3aaf28707-git - a patched version of 1.0.2 for COUCHDB-885
            Reporter: Alex Markham


A largish couchdb database was running through its view compactions (we run 3 times a week)
when it stopped responding to calls. I only realised after the event when the logs of queries
to couch showed very long response times.

The last thing in the logs is: "View index compaction complete for <View Name>" and
then a bunch of stack traces, lasting a couple of minutes.

Couch is now reindexing the whole of that <View Name> which will take hours 
Perhaps because it got corrupted during the compaction?

eg.
