Suddenly I found out that in the pool`s log I'm getting a lot of those
errors :

[jiradb](jiradbuser) - 2018-05-10 23:58:57 - [unknown] [28259]ERROR:
unable to read data from frontend
[jiradb](jiradbuser) - 2018-05-10 23:58:57 - [unknown] [28259]DETAIL:
socket read failed with an error "Connection reset by peer"

The application owner didnt complain about any problem but I dont like it
that I'm getting that error. This error is raised sometimes every 3-4
minutes and sometimes every 3 seconds..

I can attach the logs if needed.

Some pool parameters :
num_init_children = 32
max_pool = 4
child_life_time = 300
child_max_connections = 0
connection_life_time = 0
client_idle_limit = 0

Do you recommend mybe to change those parameters ? Any idea why the error
is reaised ?
