[Opensim-users] Crash on static hypergrid link-region

[Zonja Capalini]

Hi,
I'm running two opensim instances at condensationland.com.

* condensationland.com:9000 is my Condensation Land grid, running standalone
v. 0.6.4.9561, MySQL backend, 10+ regions at ports < 10000.

* condensationland.com:20000 is my OSGrid gateway region, running in grid
mode v. osgrid.opensim.v0.6.6.10051, default sqllite backend, one region at
port 20300, regions.ini follows:

------- Start regions.ini ----
[Condensation Gateway]
RegionUUID = 14992827-25a1-414e-b6bd-481365915a68
Location = 7789,7789
InternalAddress = 127.0.0.1
InternalPort = 20300
AllowAlternatePorts = False
ExternalHostName = 87.216.55.54
MasterAvatarFirstName = Zonja
MasterAvatarLastName = Capalini
MasterAvatarSandboxPassword = ******
----- End regions.ini -------

I'm linking condensationland.com:9000 from the OSGrid instance at :20000 to
be able to hypergrid-tp to my grid. That works.

Now when I try to

  link-region 3789 3792 condensationland.com 20000 Condensation OSgrid

from my grid in the :9000 instance, I get an exception and the :20000
instance crashes.

Log follows:

--------- End opensim.log --------------

Then if I restart the :20000 instance, it relinks to :9000, and the :9000
instance still remembers the link to :20000, so that all works fine, except
that the :9000 instance hasn't got a proper thumb for the linked :20000
region and displays a blank tile in the map.

Any help would be greatly appreciated.

TIA,
