Grails with Postgress ADMIN SHUTDOWN issue

[Vadim Kirilchuk]

Hello,

I have a grails application deployed on cloudfoundry and i`am facing next issue with it:

While trying to execute some update query i get "SQL Error: Already Closed" message.

If i look at my application log, i will see this:

2012-02-19 18:55:26,683 WARN  [hibernate.util.JDBCExceptionReporter] - SQL Error: 0, SQLState: 57P01
2012-02-19 18:55:26,683 ERROR [hibernate.util.JDBCExceptionReporter] - Batch entry 0 insert into TEXTEIN_EDITING_WORKFLOW (version, accepted, completed, cost, date_created, editor_id, last_updated, unit_id, id) values ('0', '0', '0', '0.0', '2012-02-19 18:55:22.790000 +00:00:00', '15', '2012-02-19 18:55:22.790000 +00:00:00', '39', '54') was aborted.  Call getNextException to see the cause.

2012-02-19 18:55:26,683 ERROR [hibernate.util.JDBCExceptionReporter] - An I/O error occured while sending to the backend.

I`m using postgres and error code "SQLState: 57P01" means ADMIN SHUTDOWN.
How is it possible? And what does it mean?

Could you shed me the light on this?

Thanks.
