Yes I can that’s what is really puzzling me

[armandp(at)devweb2004 ~]$ /usr/pgsql-9.5/bin/psql -d birstdb -U csidba -h 172.16.26.4
psql (9.5.12, server 9.5.8)
Type "help" for help.

birstdb=#

It is almost like the authnetication stops working for whatever reason
I did check the .pgpass and all that and nothing chaged

Is there a possibility like say 70 processes try to authenticate in the same time and postgres authentication gets a bit lost ?

Thank you
