Subject [jira] [Updated] (COUCHDB-1182) Crash after compaction is completed
Date Wed, 01 Jun 2011 11:35:47 GMT

     [ https://issues.apache.org/jira/browse/COUCHDB-1182?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Clare Walsh updated COUCHDB-1182:
---------------------------------

    Description: 
When compaction is run, it seems to complete successfully (disappears from active tasks),
but then at the end or a minute or so afterwards couch crashes [EDIT: that's a bit dramatic,
it logs a crash, it goes up a few levels of crash, but doesn't get all the way to crashed
before it starts working again].

This has happened twice so far, I am attaching logs for both occasions. The 'huge chunks of
numbers' are all in a single binary array (ie no structure has been removed) and are hundreds
of pages long (hence removed). I have truncated the logs as the same error appears three times
as the supervisor is restarting child, and then the rest of the chain upwards as it gradually
folds into a heap was very long. If any of this chain (or any other information) is needed
please let me know.

Thanks

This has happened twice so far, I am attaching logs for both occasions. The 'huge chunks of
numbers' are all in a single binary array (ie no structure has been removed) and are over
3 pages long (hence removed). I have truncated the logs as the same error appears three times
as the supervisor is restarting child, and then the rest of the chain upwards as it gradually
folds into a heap was very long. If any of this chain (or any other information) is needed
please let me know.

Thanks
