[kepler-users] Problem with PN director

[Edward A. Lee]

PN wraps every actor in an infinite loop that executes in it's own thread. I think what is happening is that the director is detecting that no tokens are available and is killing blocked threads to stop the execution. This would be normal, I think.  How else would you stop a blocked thread? The odd thing is that this exception should be caught and not reported.
