Let me guess, you're running PHP and using pg_pconnect?
Bad idea, unless you know exactly what you are doing.
I suggest one of two solutions.
1: Discontinue use of pg_pconnect. Performance gains from pg_pconnect
aren't that great on a lightly loaded system and the inherent problems
that pg_pconnect can produce are much worse than any small performance
gain you might see.
2: If you really need pg_pconnect, then you have to configure your apache
web server and your postgresql database the right way.
assuming a single db and a single apache server, you need to edit the
apache server's httpd.conf file to change the MaxClients value to be LESS
than whatever you set the max children in postgresql to. Postgresql
defaults to 32, while apache defaults to 150. Also, leave some breathing
room for other access methods (ODBC, psql etc...)
Most setups will run fine with something like this:
postgresql.conf:
max_connections = 64
httpd.conf:
MaxClients 50
