Hi Frans,

You need to isolate what there's too many connections to. Is it the database, the http server or some other resource?

My wild "stab in the dark" is that you're using the Session In View pattern with hibernate and a connection pool setup through spring. The pool is probably exhausted and you need to increase a setting in the pool's config (and perhaps match it in the database). It may also be worthwhile to design out unintended/unused connections. eg. don't use session-in-view on pages that don't need a hibernate session.

Struts 2 is probably not a contributing factor and when you've isolated the problem you'll find better help in hibernate/spring's/others FAQ.

Apache JMeter may help too:

regards,
Jeromy
