We are testing DHIS2.11 on PostgreSQL 9.2 after converting database from
MySQL5.5. The servers are on VM ware and database server and application
server are on same physical machine connected through a virtual switch.
Some time the servers are working fine but sometimes no one can log-on to
the application. from log I find the follwoing error: (I attach the log
file)

* ERROR 2013-06-10 10:52:02,253 Application exception overridden by
rollback exception (TransactionAspectSupport.java [http-bio-8080-exec-7])
org.hibernate.exception.JDBCConnectionException: An I/O error occured while
sending to the backend.

OS : Ubuntu 12.04
