I had the same problem but I use lockmode="force" for the join activities and it works. My process has asynchronous nested forks, asynchronous java activities, and I loop over these forks up to 100 times. PS: The user guide does not mention force as one of the choices for lockmode. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/559698#559698] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
