Bug: frozen Orders and "Unhandled message StartProcessing"

Current Situation

• Order in Ready state does not start the next Job, and
  • the Agent log shows an error like

    Unhandled message StartProcessing in Actor state 'processing', Order state is Ready

  • probably the Job does not execute any Order because its process limit is reached.
• Such orders carry the (lightblue) In Progress state in JOC Cockpit.
• The situation can be caused by a number of skipped jobs in the current workflow. 

Desired Behaviour

• This should be fixed.

Workaround

• Users can suspend + resume orders in the In Progress state that are hit by the problem.
• Users should check that only a small number (1-3) of jobs are skipped in the workflow. Avoid larger numbers of skipped jobs in workflows. 

Patches

• Patches are available for release version 2.5.3 and 2.5.5. See linked article how to apply patches.
