Javier is right. We have the same issue sometimes when too many clients connect to our XMLDB. So it might be worthwhile investigating how many apps are connecting to your postgress DB. Do they all properly close the connection? It's not a Cocoon issue for sure.

Hi Paul, Your pool is configured to max 200 connections. Is your postgres configured to support this quantity? (by default is 100). The error is thrown by postgres itself so I suspect that's could be the cause. See http://www.postgresql.org/docs/8.1/static/runtime-config-connection.html Salu2 2012/10/12 Paul Joseph <pjos...@gmail.com<mailto:pjos...@gmail.com>> Hi there, I've supported a Cocoon application for many years now but yesterday a new problem was reported that I haven't' seen before. The customer was doing something relatively unusual---using a script to read a spreadsheet and automatically fill in a Cocoon CForm and then save data in a plain old database table. The error is as shown below. Not sure what setting to use for my connection-pool in the jdbc-connection-descriptor (below). <jdbc-connection-descriptor jcd-alias="WebStore" default-connection="true" platform="PostgreSQL" jdbc-level="3.0" driver="org.postgresql.Driver" protocol="jdbc" subprotocol="postgresql" dbalias="//localhost:5432/WebStore" username="*****" eager-release="false" batch-mode="false"> <connection-pool maxActive="200" validationQuery="" /> <sequence-manager className="org.apache.ojb.broker.util.sequence.SequenceManagerNextValImpl" /> </jdbc-connection-descriptor> Other than that it is Cocoon 2.1 using Java6 in Tomcat 7.x and Postgresql 9.1 with a JDBC 3.0 driver. The actual error is shown below. brgds Paul NFO: Server startup in 5045 ms org.postgresql.util.PSQLException: FATAL: sorry, too many clients already at
