> 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.
> [Sun, 17 Jul 2011 12:07:09 GMT] [info] [<0.30126.2013>] checkpointing view update at seq 1 for <DB> <View Name>
