I have developed an application using Codeigniter and PostgreSQL as the database.

Codeigniter application resides on IP 192.168.X.34 => Application server

PostgreSQL server resides on IP 192.168.X.35 => Database server

I frequently get below error in the production environment but in my local-pc I don't get any errors as such. Both production and local-pc are running ubuntu.

How can I fix this?

Update

OpenSSL 1.0.1e 11 Feb 2013

PostgreSQL version 9.1/main

There are no errors shown in the log file.

Restart the Apache at application server. Possible reason might be that Apache is using mixed connection to the database as in my case this was happening when I switched my databse server.
