Process probe profiles being deployed to a group via the the MCS are showing up in a pending state.
When viewing the processes probe via IM or Admin Console, MCS successfully creates and enables the profile but is not configuring most of the settings.
The MCS log and MCS GUI for the group is showing a message saying 'The session was closed by the remote host' and that the profiles are Pending Profile Deployment.
The mon_config_service.log shows the following message in the log repeated frequently:
The session was closed by the remote host.
Installed hotfix mon_config_service-8.5.8-HF1 to correct the issue.
This fixes various issues with the MCS deploying profiles to a probe.
