      Steps to reproduce (Required on creation):

      • the scenario is somehow unclear, why it happens
      • this kind of NPE is thrown very often

      Observed Behavior (Required on creation):

      • it looks like the import of the proces instances is stucking
      • there are more than 60K entries of a specific process definition to be imported, actually only ~17K are done

      Expected behavior (Required on creation):

      Root Cause (Required on prioritization):
