Summary0006416: Crossing a region border into a seperate region instance causes a [LLCLIENTVIEW] exception resulting in a loss of control.
Description2 separate instances running on the same grid on the same machine with one region placed on the northern border of the other. While testing border crossings between them the viewer lost control of the avatar after the second or third time going from the southern region to the northern one. The console output this error:
19:20:48 - [LLCLIENTVIEW]: Caught exception while processing OpenMetaverse.Packe
ts.CompleteAgentMovementPacket for Arielle Popstar, Object reference not set to
an instance of an object. at OpenSim.Region.ClientStack.LindenUDP.LLClientVie
w.SendLandProperties(Int32 sequence_id, Boolean snap_selection, Int32 request_re
sult, ILandObject lo, Single simObjectBonusFactor, Int32 parcelObjectCapacity, I
nt32 simObjectCapacity, UInt32 regionFlags) in C:\Users\jo\Documents\Opensim\Ope
nSim\Region\ClientStack\Linden\UDP\LLClientView.cs:line 4717

The avatar would then just continue flying or walking across the region and into the sea.
I found that after closing the viewer and attempting to log back in caused an Login Error if attempting to log into the Last Location. Sometimes the region console would log me out and other times not. When it didn't, the region i froze in initially was inaccessable and couldnt even be seen.
Steps To ReproduceCreate 2 regions adjacent to each on a grid, one directly north of the other. Flew in a circle of approximately 40 meters across the boundary of the 2 while wearing attachments (The error was never noted when avi just has wearbles on). By the second or third crossing the above error would happen consistently with different viewers and by different people at different locations.

PrimCounts issue

Yes, on the surface it looks there may be no PrimCountModule but this ought to be impossible right now since there's it's in OpenSimulator core and there's no way to disable it.

Do you see the line

[REGIONMODULE]: Adding scene <region-name> to non-shared module PrimCountModule

for the regions in these simulators?

Does this problem happen every time on every simulator run? Above, are you saying that this did not happen for an initial region crossing but didn't happen for subsequent ones by the same avatar at exactly the same place (i.e. in to the same parcel).

I see the line: [REGIONMODULE]: Adding scene <region-name> to non-shared module PrimCountModule in the console of all 3 instances.

The error happens any time i cross several times in succession when:

A.avatar is walking or flying across the border from south to north. (Not seen the error from north to south)

B. The avatar is wearing attachments. (Seemed like the more I wore the more consistently it happened.)

A map of my grid: [^]

When testing Instance 1 and 2 the Mega region was deregistered from the grid. The same error did come up between Instance 1 and the mega so it seemed to not make a difference whether it was one region or 6 region mega.

Note which may or may not be relevant is that the region owner of the mega and Instance 2 showed up as Unknown name even after viewer cache clean.
