Alright, now I understand what is going on. From the server log: org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [org.jbpm.graph.exe.Token#192] the problem is not your machine being slow. On the contrary, it is way faster than mine :) It is receiving new inbound messages in the < onMessage > branches while the transaction that executed the < pick > has not committed yet! There is already a JIRA issue for this: BPEL-198. The solution is upgrading to BPEL 1.1.Beta2, which will be released this week. Thanks for providing your logs.
