JBPM process start blocking the UI

[balazska]

Hy!

I observed that the jbpm process starting blocked the ui about 5sec.
Then I try to put the process starting in an asychronous method(raise asynch event), but I got transaction exceptions.

Any idea?

Have you tried setting  the log level of jBPM higher and see what actually causes this behaviour?
