Hi!
Maximum number of connections in postgresql.conf is more than sufficient
and we configured the CF-Servers to use connection pooling so they
cannot reach the limit set in postgresql.conf. I don't think that this
is the cause of my troubles.
Regards,
Markus

Check the postgresql.conf file for the maximum number of
connections.
It has been my experience that postgresql is not very well tuned
out of the
box. It is a great system, and I have no doubts about its
capability, but it
usually needs to be tweaked a little after a default install.
