Alright, I posted a mantis along with the results of 'show threads' here
http://opensimulator.org/mantis/view.php?id=6651
Thanks Justin!

I think this would be worth opening a Mantis for. In particular, I'd
be interested to see the results of "show threads" when this happens.
A VM thread dump would be ideal but that's a trickier proposition on
Windows.

In addition to the testing done in the previous post, I found that it
seems like the only option that seems to more
consistently let all regions load their scripts is to set
DeleteScriptsOnStartup back to true; in this case both my
systems load all scripts on their regions on both databases... But it
significantly slows down startup due to having to
compile all the scripts which is the reason I usually set it to false.

Hi Justin,
I'm running 11 regions in Standalone (No HG) configuration. 5 of
those regions do not have any scripts to be loaded on
them and very few prims to load.
I disabled 5 regions, leaving 6 regions to load at start up,
restarted OpenSim a few times (I always shut OpenSim down
completely and then restart it from the exe file rather than use the
restart command), but found that it doesn't seem
to make a difference in script start up.
Set async_call_method = UnsafeQueueUserWorkItem in OpenSim.ini and
restarted OpenSim a few times. From what I can see,
setting this seems to make the issue appear more frequently, and on
more regions than with using default setting;
though this could just be coincidence as I set it back to
SmartThreadPool and tried again with similar results.
Set TrustBinaries = false with no noticable improvement.
Set ScriptDelayFactor = 1.0 with no noticable improvement.
I also tried one extra thing, setting AppDomainLoading = false, but
this didn't seem to have noticeable improvement.
The issue seems to show up randomly and will pick random region(s)
to not load scripts for on start up. It's a
slightly older commit but I don't see the issue showing up in
3611d33 (r/22387) with all my regions enabled and the
script settings reported earlier set.
Ran these tests on two different machines with two different
databases with different content to load.

I've not heard any other reports of this yet though this doesn't
necessarily mean anything.
How many regions are we talking about here? What happens if you
run fewer regions on one machine? Does specifying
async_call_method = UnsafeQueueUserWorkItem
in [Startup] on OpenSim.ini make any difference? (this uses the
system pool for threads rather than a separate
SmartThreadPool instance)?
Also, does setting TrustBinaries = false make any difference? This
is the one relatively unusual setting you have
below. You could also try specifying a non zero ScriptDelayFactor
in case some script is managing to hog CPU.

I was noticing while testing master that sometimes when starting
OpenSim up that it is refusing to load scripts for
some
or all regions at start up. Once every thing is loaded up and the
console is ready, running the 'login status' command
it shows that some regions are enabled login, and some aren't. In
order to login the 'login enable' command must be ran
first. Once logged in it seems that no script will run on the
regions that have not had their scripts loaded at start
up, including attachments, or newly rezzed objects. Had a closer
look at the console out put and was noticing that
there
are a lot of warnings dealing with objects I have rezzed in world
that are mesh similar to below:
WARN - OpenSim.Region.Physics.Meshing.Meshmerizer [MESH]: No
recognized physics mesh found in mesh asset for
chair/c861affd-17b4-4b3c-9535-f1986ab394a9
I found that if I tracked these objects down and removed them from
the region and then restarted OpenSim, there's a bit
better chance for scripts to be loaded properly. If I put the
objects back out again and restart OpenSim then it starts
to randomly not want to load scripts in random regions at start
up. Setting DeleteScriptsOnStartup = true in
OpenSim.ini
or deleteing the ScriptEngines folder prior to start up also seems
to give better success at having scripts load
properly. It might be just my imagination and coincidence that it
is working in this way but it is my observation.
Noticed that the console seems to hang for a bit (a couple
seconds) before outputting warnings on these objects with
high CPU use. I'm just speculating on this since I'm not entirely
knowledgeable on how things work but... could there
possibly be some kind of race condition somewhere preventing
scripts from loading properly in this case?
A couple of my regions have 0 scripts on them; not sure if it
matters or not.
I normally run OpenSim with these script related settings:
AppDomainLoading = false
DeleteScriptsOnStartup = false
EventLimit = 500
ScriptDelayFactor = 0.0
AllowScriptCrossing = true
TrustBinaries = true
Is anyone else seeing this?
Thanks!
