Hi Carrie,
There is some good information about CHASE in this link:
https://techdocs.broadcom.com/us/en/ca-enterprise-software/intelligent-automation/workload-automation-ae-and-workload-control-center/11-3-6-SP8/reference/ae-commands/maintain-system/chase-command-verify-job-starting-or-running-status.html
I don't know how your job is set up but it could be something similar to having a load balancer on the agent machine and it might be looking at the incorrect node. Or maybe the CHASE timing is too short and in that case it might need to be increased.
Thanks
Richie
