Sidekiq - could not obtain a database connection within 5.000 seconds

Question

I get the following warning with Rails 4 and Sidekiq on os x on development

10:13:39 worker.1 | 2014-09-22T07:13:39.857Z 86981 TID-oug0oog10 WARN: could not          


        

Answer 1

Database connection size should be one plus the concurrency if we are using rails < 5.2 . Here is the corresponding GitHub issue. https://github.com/mperham/sidekiq/issues/4252

If there are 5 threads then the db pool size should be 6 in rails < 5.2 version
