[jira] [Created] (COUCHDB-1224) Couch crash after View compaction,
unresponsive for 1-2 mins, view reindexes from scratch
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.
[Sun, 17 Jul 2011 12:07:09 GMT] [info] [<0.30126.2013>] checkpointing view update at seq 1 for <DB> <View Name>
[Sun, 17 Jul 2011 12:07:09 GMT] [info] [<0.13656.133>] checkpointing view update at seq 2103372 for <DB> <Another view>
