Filip,
thank you for your help.
Your suggestion actually helped to identify the root of our issues: it
was not related to Tomcat 6 but instead it was an issue in the version
of DBCP we were using (a snapshot of November 2007); we have upgraded
it to the HEAD and the errors seem gone away (we are running some load
testing sessions right now).
Thanks so much and sorry for the off-topic.
