Thanks jimbojimbo,
We did reboot last night and we knew to look for .SMGR_Maintenance.lock and the file was not there. Completed a fresh install of 6.1 on the System Manager, then rolling back Session Manager to 6.1 introduced an expired certificate "bug". After 30+ hours on this, team went to rest and re-group tomorrow morning.
Thank you for the information.
