[Pgpool-general] psql: server closed the connection unexpectedly

[Ger Apeldoorn]

Hi,

I'm having a problem on one of the pgpool instances. When I try to connect through 
pgpool, it cannot connect. The other node's pgpool works fine, so both postgresql instances
are up and running.
The configuration is the same as used for the previous version, 2.2.5.

--------%<--------
postgres at db3$ psql -p9999 database_name
psql: could not send startup packet: Broken pipe <- seen this happen once

postgres at db3$ psql -p9999 database_name
psql: server closed the connection unexpectedly <- mostly I get this error
	This probably means the server terminated abnormally
	before or while processing the request.

Going directly to the local database, it works:

--------%<--------
postgres at db3$ psql -p5433 database_name
