Summary0008315: Regions table clearing
DescriptionAt the moment simulators that are taken offline via crash or process termination rather than the shutdown command leave behind an entry in the regions table. This results in regions seemingly connected to the grid not allowing entry, skew the number of connected regions and take up grid coordinates.

It would be useful to have robust periodically check all simulators in the regions table and send a "ping" to those simulators requiring a return to retain the entry in the regions table. If no return is received by robust in a certain amount of time the entry in the table would then be removed.

Obviously for grids that allow for the reservation of grid coordinates and rely on de-registration not to occur to retain said coordinates robust would need a configuration setting to turn this on or off. It would likely be a good idea to also add a field in the regions table, exempting an entry from checking for "keep-alive" by robust.

Yes robust awereness oof regions and also avatars needs improvement.
But how to do that without a major increase on bandwith on large grids mb not that easy. The optional datasnapshot is a example of that, only sustainable on small grids.

Apart from logins robust is fairly lightweight in terms of bandwidth and generally most larger grids tend to run load-balanced as is. It's not going to be fun yes, but as it is it's not good either. You win some you lose some, in my opinion a hit worth taking if it means less ugly grid map.
