We have very long background processes working intensively with the DB. So I would guess that at least one connection is almost always in use. Two just is too few connections. Even if a much larger pool would maybe not really solve the problem, it would at least make it much less severe.
If we last around a day currently with two connections, my guess would be to last many days with many more connections... -- Sent from: http://tomee-openejb.979440.n4.nabble.com/TomEE-Users-f979441.html
