WRITE_BEHIND_MAP_FOUND_CWOBJ4909=CWOBJ4909E: Domain {0} will not send updates to domain {1} for map set {2} from ObjectGrid {3} because the {4} map is configued for write-behind support in {5}.
Explanation
Map sets containing maps with write-behind loaders are not supported in a multi-primary environment.
User response
Remove the write-behind loader from all maps in the map set to enable primaires in both domains for this map set. No action is required if you do not wish to support a multi-primary topology with this map set.
