Did you try disconnecting in your before_fork hook and reconnecting
before_fork do |server, worker|
# the following is highly recomended for Rails + "preload_app true"
# as there's no need for the master process to hold a connection
after_fork do |server, worker|
# the following is *required* for Rails + "preload_app true",
Open database handles must not be carried across fork.
