The error is:

description The server encountered an internal error () that prevented 
it from fulfilling this request.

exception

javax.servlet.ServletException: Hibernate operation: could not execute 
query; uncategorized SQLException for SQL [select tproductty0_.typeid as 
typeid9_, tproductty0_.parentid as parentid9_, tproductty0_.isleaf as 
isleaf9_, tproductty0_.typename as typename9_, tproductty0_.comments as 
comments9_, tproductty0_.menuorder as menuorder9_ from 
public.t_product_type tproductty0_ where tproductty0_.parentid=? order 
by tproductty0_.menuorder desc]; SQL state [08006]; error code [0]; An 
I/O error occured while sending to the backend.; nested exception is 
org.postgresql.util.PSQLException: An I/O error occured while sending to 
the backend.

It looks like there was a crash on the backend. What do your PostgreSQL 
server logs show?
