So the problem still under invertigation, there was several updates of production with and without view role applied to service account. When role is disabled, it seems there is no problems with workspaces idling and thread locks, but replication didn't work.
We're also set up the same version and granted view role on prod-preview, tried with diagnostic tool and everything seems went fine, replication is working:

h-4.2$ cd /home/user/eclipse-che/tomcat/webapps/api/WEB-INF/lib/

cluster=RemoteSubscriptionChannel
version=4.1.0.Final (Mont Ventoux)4 responses (4 matches, 0 non matches)

Now production is again re-updated with view role and we're monitoring for idling status and thread locks.

Seems working OK on prod ATM. Closing for now.
