Hello there,

I'm running into some concurrency issues and need some help. I'm currently
using JRuby 1.7.12 and Rails 4.1.1. Every now and then i'm getting this
error:

ActiveRecord::ConnectionTimeoutError (could not obtain a database
connection within 15.000 seconds (waited 15.001 seconds)):

  vendor/bundle/jruby/1.9/gems/activerecord-4.1.1/lib/active_record/connection_adapters/abstract/connection_pool.rb:190:in
`wait_poll'

Our database pool is set to 20 and a checkout_timeout of 15.

Has anyone seen this issue before?
