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
