Hi,
Maybe you can give me copies of those prims so I can take a look to what is happening.
- Many debug messages where made for devs to read logs like this, not end users
- asset type 0 is texture ( or sculpt map )
- grids can't scan all assets to fix creator id, just because they now have 2 many of them.
And creator ID had been broken in several different ways.
- only one object not giving error is a bug ill fix soon.
But first I would like to see why and what is reported missing.
Yes old grids are filling with very broken or bad content, but not easy to clean that without loosing the 0.01% old things that are good.
Even old freebies shops like wright plaza have now tons bad content.
Ubit
Ps: why do you run that cache scan at all startups? That’s a heavy thing.

As I said in the original post these prims have no scripts in them so there
are no scripts calling any missing UUID's since there are no scripts.
These prims are all simple prims that make up the helicopter. They actually
have names of the link number and the one in the message showing is link
#16. I placed several copies of this one prim on the test region to see if
each time I added another prim the error count would increment by the number
of those prims minus 1. If the asset is actually missing why can you always
rez one of the prims without any errors? Only if you add another of the
same object will you get one error not two. If you then delete one of them,
and it does not matter which one you delete, you will once again get no
errors.
Example: I rez two Bell Ranger Helicopters, one named Bell Ranger 1 the
other Bell Ranger 2. I first reg Bell Ranger 1 and then do a region
restart. Clean reboot with no errors. Then rez Bell Ranger 2 and do
another region restart. This time one of them will give an error. Usually
the second one rezzed but not always. This time it gives errors with both
of them rezzed and it is telling me Bell Ranger 2 is missing some asset. Ok
now I delete Bell Ranger 1, the one that did not show any errors, and do
another region restart. Presto, now Bell Ranger 2 has no errors. This does
not make sense.
The errors are being caused by 3 of the 33 prims that make up the
helicopter. I decided to delete those 3 prims, rez a 30 prim helicopter,
take it back into inventory and then placed 15 of them on the test region
and did a restart. Yup clean restart with no errors.
Now those three prims I removed from the helicopter do not contain any
scripts. they don't contain anything. in "contents" you see a blank list of
nothing.
I took one of those defect prim parts of the helicopter, took everything
else off the region so there were no prims on it at all, did a "backup"
command to persist an empty region, and placed two of these single prim
objects on the region. Yup it gives one error not 2 errors. Looking at the
log it shows there are absolutely no scripts at all on the region. So your
idea this is something in a script does not hold water.
One thing I did notice is that all 3 of the defective prims are sculpted.
Not being a creator, I have no idea what complexity this makes them. There
sure isn't much in the edit window that tells you what might be wrong with
them. Obviously something is wrong.
Visually they appear to be perfect. Is there any way to fix these defective
prims by performing some kinds of edits on them? Maybe export it to an OAR
and then import it back in?
Lets make this very simple.
Here is a log from the region restart with only 2 defective prims on the
region. They are called (#16 prim a) and (#16 prim b) They came from my
inventory from the same object and I changed the name so it would be
different. They are identical in looks and are one of the defective prims
from the helicopter.

2018-09-09 19:30:50,502 DEBUG [SCENE COMMUNICATION SERVICE] Informing 0
neighbours that region TSim SBox is up
There are some interesting facts about this simple test.
In my region database there are only 2 objects in the database and they are
these two objects I have on the region.
The missing asset UUID listed in the debug information isn't in the region
database so I have no idea what the missing asset even is.
Another interesting thing is that there are four debug messages for the
missing creator who is apparently no longer on OSgrid, or OSgrid has changed
their uri name and do not support previous names they might have used. But
why 4 debug messages? There are only 2 objects on the region and each
object only has the UUID of the creator in it once. I count 2 not 4 so why
is debug giving 4 messages when there are only two objects? And why has
OSgrid abandon a uri name and not made any effort to update existing asset
server items to the new uri name?
I know who cares. well unless you do not give a crap about using up tons of
server resources, everyone should care about useless, wrong, redundant,
information spewing out from opensim unless it is actually telling someone
something useful. I guess using cycles isn't a concern but when it happens
over and over, you are using billions of server cycles doing absolutely
nothing, Cycles that could have been used to perform useful functions.
Is any of the information the debug statement has in it useful? What is a
type 0 asset? Does that give some clue as to what is wrong?
OSgrid has so much bad content I almost wish they had started over fresh
after the asset server crash. At least then content could have been
filtered and bad contend prevented from ever finding it's way onto the grid.
Without content opensim is a useless program. That should make bad content
enemy number one for a program, not something you just put up with.
I can't believe there isn't something I can do to fix this particular object
so that it can become "good" content and be a good player on OSgrid or any
grid. Is there a rule that once a prim is bad it will always be bad, and
can not be fixed? Is there a way to remove this mysterious missing asset
reference since it apparently isn't needed?
if I can figure out a way to fix this broken content, I can make it good and
then give a good copy to my residents and get rid of these pages of errors
and reduce region start up time to a reasonable amount of time.
And about the missing creator, can I simply edit that UUID in the database
to be a NULL UUID and get rid of that error. A simple script on my server
could easily do that to all my database entries that matched un-resolved
uri's. And my logs have thousands of them. Most are from offline HG grids.
Lastly the elephant in the room is, why no errors if only one copy of a bad
prim is on the region?

Search this uuids in your scripts for particles in the object.
You have this alert when a texture is referenced in a script but this
uuid do not exist in database.
For example textures for particles in a old steam or smoke script.
The script for steam work with a "null" texture but the texture
referencen is not in your database.
Change the lost uuids in the scripts if you like or ignore this alert.
Is not a bug.
You have the same error for the same scripts when do a oar file.
