> Every now and then we see commit failures in a cluster when many sessions try 
> to update the same property or perform some other conflicting update.
> The current implementation will retry the merge after a delay, but chances 
> are some session on another cluster node again changed the property in the 
> meantime. This will lead to yet another retry until the limit is reached and 
> the commit fails. The conflict logic is quite unfair, because it favors the 
> winning session.
> The implementation should be improved to show a more fair behavior across 
> cluster nodes when there are conflicts caused by competing session.
