Default stack configuration may lead to lost calls

Given I have installed a Wazo server
Given it is used with the default configuration
Given it has good performance hardware (lots of CPU, RAM and IO)
Given it is used extensively, with many calls per day and using lots of APIs
When a call comes in
Then the call fails and is hungup

Expected: the call is processed normally

Technical details:

• wazo-agid fails with the following error:

• Wazo services use a maximum of 125 threads

• PostgreSQL has a default limit of maximum connections of 100

We should reduce the default number of threads or increase the maximum number of connections.
