Re: Issue with postgres connectivity

Hello All,

I am facing a big problem in postgres connectivity using php application. It is taking almost 10 sec for connection establishment. All my applications were working perfectly 2 days before. Yesterday just it started giving problem. Using pg-admin also it is taking time to connect as well as same with opening server status window or with sql query window.

Postgres is installed in linux environment. Don't know whether is it due to some virus or something else.

Please provide me with some guidelines. Ask me any queries.

Thanks,
Arindam

Thanks Reinoud for quick reply. How can I test it? Is there any way?

try adding the IP addresses of some of the clients as seen by the
server to /etc/hosts on the server. see if that helps.

try connecting to the server locally using 'su postgres -c psql'
see if that's slow too.

What I have seen is that, when I am trying to connect the db server from application server using ssh, the response was very slow. While from db server to application server it is very quick as usually.
