But maybe we use some other queries which cause such problems with this "old" driver.

In our production we have a james server with many costum mailets + matchers. We use -Xmx512m -Xms64m as JVM_OPTS. We had a memory usage of 257MB on monday (which i told Noel). Now its 220MB. So it was dropped. We use mysql-4.1 + mysql-connector-5.0.3 and db for spooling. > --- Noel > bye Norman
