We had a *very* interesting experience today due to our starting usage of POUND.
Two webservers, both configured to have 60 database connections.
One database, configured to have 100 maxconnections.
THe site stopped (no replies anymore) on a regular basis and we had no clue what has happened, until we shut down one of the two webservers and then everything went smoothly.
What I am saying is this, and maybe we are just very very unlucky ...
If you run multiple webservers in front of your database make sure that you do not exceed the maxconnections of the database. Otherwise you webservers will freeze as they try to get a new connection, the new connection is not granted and for whatever the reason AOLserver / nspostgres waits for new connections instead of just reusing the old one :).
