I need the trace of the cause of the SchedulerException as well.

This is the stacktrace that is reported, I will check if I can get more out.

Description changed from Problem:SchedulerException ... to Problem:SchedulerException ...Added a more complete stacktrace. this is now on version 1.1.3. It looks like something is trying to schedule a task when the scheduler is trying to shutdown, is that possible? My tests do a lot of server start and server shutdown before and after tests.
Found this post relevant (I think the source is credible :) http://pveentjer.wordpress.com/2008/02/06/are-you-dealing-with-the-rejectedexecutionexception/

We should probably remove both Scheduler.shutdown and Scheduler.restart

How do you deal with a rejectedexecutionexception when something is scheduled to be run in the future? :-)
Are you actively shutting down the Scheduler?

Assigned to set to viktorklangStatus changed from New to FixedAnd this only happens for testing?
If so, it's fixed in 2.0 since the scheduler won't be stoppable :-)

Hi Guys,
It only happens during testing, and when I remove Scheduler.shutdown from the before/after stuff in the tests the problem doesn't occur anymore. I agree it is fixed in 2.0 (not stoppable).

Hey Raymond,
thanks for the feedback
If you have any thoughts on how we can improve the Scheduler I'd love to hear them!

The following exception occurs when I run a suite of tests that all stop actors on teardown. I will try to add a reproducable unit test.
akka.actor.Scheduler$SchedulerException: TimeoutMarker(0) could not be scheduleOnce'd on Actor[akka.testkit.TestActor:1bf1baa0-a6f5-11e0-9405-0019d2b39ec9]
