Dear Team,

We are facing issue whenever application is connecting to pgpool 4th Node.

We have 4 Applications and 4 pgpool nodes, at any point of time Application can able to connect only 3 pgpool nodes, when we are starting application services on 4 pgpool node we are getting below error messages on application logs and also psql command on pgpool is getting hanged..

Application Logs:
