I am getting this error: 'could not obtain a database connection within 5 seconds (waited 5.001017 seconds). The max pool size is currently 16; consider increasing it.' First I got this error, I bumped up the count from 5 to 16. But it's still happening and i am the only one test out the database. Why is this happening when I am the only user? I am not on rails btw. I am using: ActiveRecord::Base.
