This is the exception you usually get when the connection times out.

There are a few problems with this flag. However with bundle
persistence it should work as far as I know (because in this
persistence manager, autoCommit is on when idle). My recommendation is
to use it for BundleDbPersistenceManager.

Bundle persistence is faster.
