(Cross post from Performance & Tuning)

Hi,

I have a default installation of JBoss 3.2.1 running on WinXP and Sun j2sdk1.4.2

I have a web app which sends a message to an EJB (session facade) which logs a message in the DB (MsSQL 2000)

Anyway, if I setup jmeter or OpenSTA or Junit perf to connect more than 20 times, I get :

Any ideas? I have tried fiddling the threading settings in jboss-service.xml in the jetty.sar directory?

Please help as I have spent about 2 weeks now reading the docs and searching the forums!
