[Pgpool-general] Problems running pgpool, no access to db

Tue Dec 12 15:42:44 UTC 2006

Hi,
I have setup pgpool-II from CVS on a ubuntu edgy system. When I try to
connect to the db the connection will be closed imediately.
The client says:
psql: server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.

This is the log. I can not find the reason why. At the end is the pgpool
configuration.
