While creating workflow jobs, job name indexes are not getting generated in sequence
Workflow steps behavior is not consistent (abnormal) e.g. unexpected/unwanted dropdowns are being shown for steps
When initiated multiple jobs, each job halted at different step
Workflow performance is poor
Our environment has multiple network interface controller (NIC) cards or DNS entries, and we already followed the Configure ArcGIS Server in advanced scenarios documentation to handle it.
Just adding onto my experience with Ranga's point 2 observation on workflow steps having unwanted/unexpected drop downs. While my Workflow Manager Server is not HA, it is federated to a HA Portal and Enterprise. I would also like to know the cause of why a step that has not been configured to run in parallel (i.e., only having 1 path in and 1 path out) would result in the unwanted/unexpected drop downs.
A defect bug is logged by Esri for the inconsistency that has been observed with the Job ID creation in the HA workflow manager. Details of the bug is as follow:
Defect: BUG-000155792
Synopsis: Workflow Manager jobs not working in High Available site.
