Everything has been working fine for years. Today we noticed out Service Desk instances in Process Automation were stuck in running status. They are all hung on the sdm_login operator. If I run a sample process which does not contain a connection to Service Desk, the instance completes properly showing the orchestrator is working properly.
It seemed there was a stuck connection thread between ITPAM and Service Desk. Restarting ITPAM orchestrator did not resolve the issue. Confirmed there was a short network issue and after it came back up the connection between ITPAM and Service Desk no longer worked,
Release : SDM 17.1
Component : Process Automation
Stopped Service Desk service.
Restarted Service Desk service, confirmed back up and running
Restarted Orchestrator service.
Once this was complete, all the instances completed and proceeded as expected.
