Issue/Introduction

UIM OC Upgrade hangs during the Verify Robot process: 

Environment

UIM with hundreds of robots that report to the Primary hub

Resolution

The OC Upgrade Verify Robot process is expected to take a while when hundreds of robots report to the Primary hub.

During this process, the install runs a probe_list callback for probes below against all robots that belong to the Primary hub
automated_deployment_engine
data_engine
discovery_server
maintenance_mode
mpse
nas
sla_engine
ems

Example of entries seen in the C:\tmp\ia\oc.log
/mydomain/primary_hub/myhub did not respond to probe_list (name=automated_deployment_engine): (4) ...
/mydomain/primary_hub/myhub did not respond to probe_list (name=data_engine): (4) ...

Run the OC installer again and allow enough time for install to complete.
