database failure..

Hi,

I have a database, which just happens to be the main database on a
RAQ4..(cobalt)
that even when recreated it still dies, even before readding any
tables..

Welcome to psql, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help on internal slash commands
       \g or terminate with semicolon to execute query
       \q to quit

cobalt=# \d
The connection to the server was lost. Attempting reset: Succeeded.

I can't dump either..

getTables(): SELECT failed.  Explanation from backend: 'pqReadData() --
backend closed the channel unexpectedly.
        This probably means the backend terminated abnormally
        before or while processing the request.
'.

Any idea what might be causing this?

Regards

Jason Frisch
