Thanks for your answer Maciej. I will look into version 6.
I don't understand how to use overdue timers. I do have a clustered environment. Let's say I have a couple of hundred thousand process instances that are watiing at timers, which can be up to a couple of months from now, how do I know which sessions to reactivate? If I had a list of session that needed to be reactivated I would gladly just use an EJB scheduler to do that.
Thanks,
Mason
