MCS profiles seem to be stuck with the following status:
latestDeploymentSummary = "Successfully Performed pre-requisites for deployment..."
configuration_reader_service_probe.log contains:
<Date> ERROR [Thread-44, com.ca.uim.probe.mcs.readerService.secondary.SecondaryConfigPusherThread] Failed to componse configuraiton pds for hub: /<domainname>/<hubname>/<robotname>/hub
A robot attached to this hub is in an incomplete state missing spooler probe. The configuration_reader_service probe is stuck trying to communicate with the robot, but the missing probe is not there to respond
Only one robot in this state can cause all profile deployments to stall
Redeploying the robot and correcting the installation (or removing the problematic robot all together) resolves this issue.
The MCS profiles are able to complete deployment once all robots are complete and functioning as designed.
