> Project: CouchDB
> Issue Type: Bug
> Environment: Erlang 1:14.b.3
> CouchDB 1.2.0a-f7cc8fa-git
> Ubuntu Lucid 10.04 64bit
> Reporter: Alex Koshelev

> It worked some time ago but now there is constantly the error. If I restart
> CoucDB it will solve this issue. Updating the desing doc also solves the
> issue.
> With debug log level I get this messages:
