I also set the threads to 2048 and don't let my cache expire. About the
only time I have a problem with phantom meshes is on those rare
occasions I nuke the cache, and then a second restart of the region
clears everything up.

Wow. Problem solved. I was using MONO_THREADS_PER_CPU=2048, but
somehow the cache needed to be rebuilt. Everything works great now.
Thank you so much for helping me.

When a sim starts up, it tries to fetch all the mesh assets so it can
construct colliders for any that need them. Usually many of these assets are
in the region asset cache and the sim can pull them from there rather
quickly. If they don't exist in the cache for whatever reason (new region,
cache expiration, etc.), they must be fetched from the asset server. If the
asset server is slowed by many requests or the sim tries to make too many
requests at once, some will time out and the asset will not be available and
the sim will not make a collider for them. The result is a phantom object.
Two things can help: if you are using mono make sure you set the
MONO_THREADS_PER_CPU environment variable to a reasonably high number which
will increase the number of concurrent requests; I use the following to
invoke OpenSIm:
env MONO_THREADS_PER_CPU=2048; mono --server OpenSim.exe
and the following to invoke Robust:
env MONO_THREADS_PER_CPU=2048; mono --server Robust.exe
Also you can populate your region cache with the following OpenSim console
command:
fcache assets
Restart your region after doing this and hopefully it will help with your
problem.
You may also consider setting your flotsam cache expiration to never expire,
especially if the region doesn't get much traffic and is seldom restarted.

Hello!
I upgraded OpenSim from 0.7.6 to 0.8.1 running on Ubuntu 14.04/Mono
3.10. I kept ODE physics for the time being, but with BulletSIM the
issues are similar.
I created a staging environment and copied the MySQL database from
production to staging.
When I start the regions, mostly all mesh objects are rezzed with
wrong phantom settings.
They are phantom when they are not supposed to be phantom.
If I manually set phantom on/off with the viewer for each item, that
will fix it, but it is a lot of work.
I tried the 'fix-phantoms' from the opensim console, but it doesn't
work from me.
I looked at the code for the fix-phantoms, and this is what it does
for each scene:
s.ForEachSOG(so => so.AbsolutePosition = so.AbsolutePosition);
Is this supposed to work in my use case as well?
Any suggestion on how to fix phantoms overall?
Thank you in advance.
