[Opensim-users] Vicent.Silvester attention - issue lost objects in Version: OpenSim 0.9.3.1 Nessie Dev

[Luisillo Contepomi]

Hi Mr Silvester.

Please excuse my poor level of English.

I dont know if report this to the mantis or not.

Could you perform the tests I've outlined here to try and confirm these 
problems that I'm experiencing almost continuously in the development 
version?

"[11:51 AM] Vincent.Sylvester @hg.zetaworlds.com: Had a strange thing 
happen a couple days ago. After simulator reboot items were missing, but 
only specific ones containing a script and animation. Either this was 
just bad shift copy or some other bug being masked by cache. Hasn't 
happened since thankfully"

Vicent I'm seeing this situation constantly in the current development 
version.

Test 1
------
1. Start a new, clean region with a MySQL database (Robust+1 region of 
1024x1024).

2. Import any OAR file and observe the list of how many objects have 
been retrieved and created in the region.

[ARCHIVER]: Loading ### scene objects. <------

3. Run backup and quit.

4. Start the region with opensim.sh and see how many objects the region 
now has.

[SCENE]: Loaded ### objects from the datastore

Did it load the same number as the OAR file?

If it's not a very large region, you can quickly find out what 
disappeared during the restart by visually browsing it.

If something is missing, restore the OAR file and repeat the process. 
Restart and check the number of objects in the scene.

If all the objects are there, modify some furniture and reset again the 
region.
(reset mean "backup and quit")
Look for the modified furniture. Have those objects disappeared, or have 
lost others?

I can only use the development version if, before session exiting, I 
create a new OAR file every time I've made a change.
And when I start it up the next time, the first thing I have to do is 
restore the OAR file. Otherwise,
I have to waste a lot of time looking for what's been lost.

Now I will monitorize this region next days. A shutdown and start by day.

for now the 80% restart lost some previously modified objects.
