after upgrade from sys-libs/glibc-2.13-r4 TCP JDBC connection to Postgresql server at 127.0.0.1 from 32-bit Java application is randomly disconnected. Both server and client are reporting connection closed. It doesn't happen with 64-bit Java applications.

I was wrong. It happens also with 64-bit Java applications.
Created attachment 315051 [details] Logs, config, application client Application steps: scroll, click and wait, error occurred in less than 30 seconds.
I can't reproduce with client and server running on OpenSuse 12.1 32-bit (glibc 2.14.1) or server running on Gentoo 64-bit and client running on Ubuntu 10.04 32-bit VirtualBox virtual machine.
What Java runtime do you use?

kernel update to 3.2.20-hardened didn't help
booting non-hardened kernel 3.2.20 didn't help

It happens also with dev-java/icedtea-7.2.2 java version "1.7.0_04" OpenJDK Runtime Environment (IcedTea7 2.2) (Gentoo build 1.7.0_04-b21) OpenJDK 64-Bit Server VM (build 23.0-b21, mixed mode)

There was a bug in client application.
