I tried to deploy a simple process that just has 1 script task that prints something out, sleeps for a while and then prints something out again. I uploaded the bpmn to guvnor and built the package. I can see the process in the jbpm-console, but when i try to start an instance, and click refresh so that i can see the running instance, it gives me the following error in the logs:
ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (http--127.0.0.1-8080-2) Timeout trying to lock table "PROCESSINSTANCELOG";
Is there a step i'm missing? maybe a persistence configuration change somewhere? I am using whatever configuration comes with the demo install.
thanks,
Dave
