> Many of the housekeeping/background tasks can be turned off in case of having multiple instances running parallel. 
> Some are controlled via the housekeeping node configuration, others are not started if their frequency is set to zero.
> The DB-Notification cleaner unfortunately doesn't have this functionality which makes all instances to race for the lock on the backend HMS database. 
> Goal is to add change to be able to turn cleaner off in case if there are multiple instances running (be able to bound it to the housekeeping instance).
