[Opensim-users] Anyway to verify the database

Sat Aug 18 10:05:33 UTC 2012

Seems I spoke too soon on issue 1. Those pesky intermittent issues never 
pop up when you're actually looking and testing for them =) But I 
believe I've come up with at least a partial amount of steps that I 
think might be contributing to it:

I am running git r/20019 for these steps

1. Rez an object that has multiple links to the ground. (In my case it 
is usually attachments that I've rezzed from inventory to unlink and 
make modifications on; although I am unsure if this makes a difference 
or not)

2. Unlink the object and spend a little while (perhaps 10 or 15 minutes) 
making modifications such as shift copy of prims, adding scripts, 
changing prim sizes, textureing, etc.

3. Either delete the finished object or take the it back into inventory.

4. Upon relog the object will reappear (or perhaps random parts of the 
object if it was deleted and not linked before hand).
     a. This is also visible to other avatars to after they relog.
     b. If attempting to take the object again or delete again it will 
be back again after another relog.
     c. The object will persist until server restart where it will 
reappear again, but can finally be gotten rid of for good by means of a 
delete or take to inventory.

A few things that I have noticed when the issue triggers:
     * When removing a multiple selection of prims, only the root prim 
of that selection seems to persist removal, resulting in the appearance 
of most of the rest of the object still being there upon relog.

     * When examining the MySQL database at the prims table using SELECT 
count(*) FROM `databasenamehere`.`prims` the prim count goes down by one 
even though multiple prims may be selected for removal.

     * If the server is restarted the affected objects can be removed 
and it will be persisted.

Unfortunately it doesn't it trigger consistently applying the above 
steps and I've not yet found a way to consistently trigger it.

I've created a mantis for this particular issue here:

Good luck with the other two issues though Rick!
