Googling suggests that this could occur if you're recycling client-side connections so fast that the old port number assignments haven't timed out yet. That's not a Postgres bug, it's inherent in the TCP protocol specs. > The shell script does the following: > a) Connects to postgres database server using psql. > b) Issues a single select statement on table with 200 rows . > c) Writes the results to a text file. There is a large body of evidence to the effect that issuing only one query per connection attempt is a performance-killer. Don't do that, at least not more often than you have to. This particular symptom is a new one on me, but there are lots of other reasons not to do it. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
