> The compaction of a view (created with CouchDB 1.3) failed due to view_du=
plicate_id. The database to which the view belongs was created with 1.2.x b=
ut compacted (with the 0-byte-compact-file trick) with 1.3.
> A full log of the failed compaction can be found at
> https://friendpaste.com/1AL050bzwyLCa9KJUKJw1u
> I experienced the same behaviour already with previous versions but assum=
ed it might be gone with 1.3, but this seems not to be the case.=20
> When such duplicates happen (and appear during compaction), they seem to =
be at the beginning of the view index. The view in question has the followi=
ng _info:
> {noformat}
> {"name":"listeners","view_index":{"signature":"854a8065b438b3e53fcdbbe0a7=
9a8e80","language":"javascript","disk_size":2679632207,"data_size":10266140=
11,"update_seq":58353111,"purge_seq":0,"updater_running":false,"compact_run=
ning":false,"waiting_commit":false,"waiting_clients":0}}
> {noformat}
> Compaction stopped with a 39M large .compact.view file.
> Also the problem seems to happen only one some machines.
