Last week we tried to use the 8.1-407 JDBC 2EE driver with PostgreSQL 8.1.4 on Debian. We use data sources in JBoss. The web application always run out of memory with this driver. Then whe changed back to driver 7.4 and everything is OK now. I think there must be a memory leak somewhere in the newest driver because we don't handle the driver directly, but JBoss does.
