Hi Ronald, Thanks a lot for the suggestion. With async=exclusive I don't get any exception at all. Hoever, the actions inside the nodes, are executed sequentially and not in parallel. I am deploying the framework from a class, and have running the JobExecutor with several threads in a different JVM for having parallel processing of the nodes and actions.. Any other suggestion ?
