Steve, Sure send it along, it is likely that your backend doesn't have enough available connections Dave -----Original Message----- From: pgsql-jdbc-owner@postgresql.org [mailto:pgsql-jdbc-owner@postgresql.org] On Behalf Of Stephen Ingram Sent: Thursday, March 14, 2002 4:44 PM To: Dave@micro-automation.net; pgsql-jdbc@postgresql.org Subject: Re: [JDBC] maximum java process postgres connections On Wednesday 13 March 2002 10:59 pm, Dave Cramer wrote: > As many as the backend will allow > > Dave > Hi Dave, Sorry for the delay.

Steve- As Dave said, it sounds like you're running into a back-end limitation, so in your attempts to reproduce the problem, you may want to try actions that would load the database with more connection requests. If you are running a web application it is very easy to hit this limit when you aren't using a connection pool, since you'll be opening a connection for every browser session if there isn't a method to share them. -NickF > -----Original Message----- > From: pgsql-jdbc-owner@postgresql.org > [mailto:pgsql-jdbc-owner@postgresql.org]On Behalf Of Stephen Ingram > Sent: Thursday, March 14, 2002 4:44 PM > To: Dave@micro-automation.net; pgsql-jdbc@postgresql.org > Subject: Re: [JDBC] maximum java process postgres connections > > > On Wednesday 13 March 2002 10:59 pm, Dave Cramer wrote: > > As many as the backend will allow > > > > Dave > > > > Hi Dave, > > Sorry for the delay.
