I just got the forms.xml going and put up a couple processes, but am getting this intermittent error. I dont see this happening in any particular spot, just sometimes.
I see it in a couple other places on the forums, but not in terms of the new jbpm work.
I have 20 connections, but only tested the sample processes, so it should def not have run out of connections.
And I have to restart the server for it to get connections again.
Full Error
