With a required custon field checked, SPS 2010 gets stuck in starting.
Uncheck the required field, workflow completes without a hitch.
Changes to Server:
Applied updates for the April 2013 accumulative updates
Checked the following:
The workflow is not saved or trying to run under the system account.
The workflow is set to automatically start when a new item is created.
The workflow has been reduced to a basic copy file to another workspace for testing purposes.
Any ideas I can look for
