Fail in stress test

alexisgc — Mon, 18 Apr 2011 23:20:27 GMT

Hi all,I've run a stress test for a basic flow in activiti, this flow start when a message arrives to a RabbitMQ queue.For this stress test I put 30,000 elements in a queue and then run mi JBoss server with the activiti process to consume the messages.In only 26,757 cases the flow end satisfactorily

Seems to be something wrong with classloading:
java.lang.NoClassDefFoundError: validationRules/ValidateField

Are all dependencies of your custom java code present in JBoss?

Thanks for your reply frederikheremans,

Well I think this isn't a dependency problem because if this is a dependency error would not have been possible to run the flow in 26,757 cases.

I think the message: "org.activiti.engine.ActivitiException: Error while evalutaing expression" indicates that some expression language don't have a good response when is overloaded. Maybe I'm wrong (I hope so) but I don't have any other idea that can cause this error.

Hi Alexis,

Could you attach the full diagram code (the .activiti file at least) to this post?
That makes it a bit easier to understand your process flow implementation.

Best regards,

Thanks for your reply Tijs,

This is is my bmpn20 file, I've attached the diagram code in my first post (that's the full diagram).
I had to change some names to avoid compromising corporate data where I work.
