Good day I have a business automation system that uses the Postgres database.

I have a problem that is very common in my clients. I am using the 9.5 version of Postgres and "nothing" one postgres process is suspended and can no longer close it or return to normal, there the database lock, and only starts restarting the computer, a customer has times what happens to the bank continue working more does not accept a new connection. The seviço postgres is with the status Running, but not for no more restarts.

-already tried to change the Secondary Logon service to automatic and did not work.
