 Now that we have a Rake task to copy MongoDB databases, we are facing the next problem. We store images on Amazon S3 and each environment has its own S3 bucket.

 We rolled back to 1.3.1 and were running fine in production for a long time. On Friday, we started seeing intermittent _deadlock: recursive locking_ errors from the driver and our site was struggling to stay up. Very quickly the error rate rendered it unusable. A Google search yielded Mongo Ruby driver bug [RUBY-274](https://jira.mongodb.org/browse/RUBY-274), describing the exact error, which pointed a Ruby 1.9.2 threading issue [#4266](https://bugs.ruby-lang.org/issues/4266), explained in [this blog post](https://web.archive.org/web/20120228164435/https://blog.stochasticbytes.com/2011/01/rubys-threaderror-deadlock-recursive-locking-bug/).

 Kyle, the maintainer of the Ruby driver at 10gen was replying to [RUBY-274](https://jira.mongodb.org/browse/RUBY-274) and told us to upgrade the driver to 1.5.2. We did. All tests passed (we have over 2000) and our staging site was operating normally. But after pushing it in production where we have a replica set, we were now seeing a different error: _stack level too deep_, with _/app/.bundle/gems/ruby/1.9.1/gems/mongo-1.5.2/lib/mongo/util/pool.rb:72_ on top of a cut-off stack trace. By then I haven’t gotten up from my chair for six hours straight and you bet I was thinking the Ruby driver was the worst piece of crap as I was angrily typing [RUBY-393](https://jira.mongodb.org/browse/RUBY-393), a knee-jerk reaction.
