What does the entry "WorkflowInstacesPerMinuteTreshold" in "DocuWare.Bpw.Service.exe.config" stand for?
(Note that the entry is not "Threshold" misspelled. That is how it has been defined).

This entry is new in DocuWare 6.11.
It defines how many workflow instances per minute for the same document and workflow version are triggered.
With the default value "10" a smooth operation can be ensured.

If the value is increased, the workflow will be unpublished automatically and the workflow controllers will be notified by e-mail.
