my first impression is that you do not use jbpm as it was inteded to be used. Holding on to a context blocks the engine for other processinstances to run. Getting a new context each time is not expensive, so get one, signal it, keep the token/processinstance id somewhere and go on with other instances. Once needed, get a context again, use the token/process id to retrieve the instance and signal it. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4023914#...
