Crashed and Burned! FG falling over...

10 Jun 2018 12:57 #38854 by Algernon
This is a new thread for group discussion about FlightGear instability and individual technical issues. It could get busy - in fact, FG stability issues are so prevalent that it might even justify its own subforum at some point! But for now, this is the place to throw our collective problem-solving prowess into the ring...

Right now my FGFS is hosed...not sure why but even my gathering of TerraSync Scenery direct using Python has stalled. I can't start FlightGear as wehn I do, it automatically tries to top off the Scenery using automatic download even if it is switched off in the launcher.

And then it stalls and sits and spins....my personal belief is that FlightGear is trying to update TerraSync (whether it has been told to or not) and the TerraSync Server is limiting how much data one can pull from it in a given period of time or it's just plain having connectivity issues that may be due to where the machine asking for the files is located.

I'm convinced it's related to Scenery Downloads but can't run it off line or even if automatic download is disabled in the launcher because FlightGeart is trying to access the Scenery Server even if I tell it *not* to do that.

A bug in the Preferences?

Who knows...I did manage to fly some last evening late but have not been able to start FGFS again this morning even with a fresh download/install. It's fucked...I'd love to believe it's all in my machine but everything else, all other programs and apps are working just fine.

I'm frustrated to pounding on the table but I'll try and get my head out of my ass and coordinate with others later Sunday.

edit: Even running Python to gather TerraSync Scenery has crashed/stalled now. The Server (and I suspect the MP Servers) is/are playing games. Maybe not Worldwide but from North America all of the Servers are "breaking up" and available only for a few minutes at a time.

Cool - I'll be here usual time and we'll see if we can get anywhere between all of us. I reckon you're right about the scenery downloads thing - I reckon first thing to try is running it from the command line instead of the launcher, with just one very basic scenery folder pointed at, and see what it does.

Up and running for now....

C:\Users\username\AppData\Roaming\flightgear.org

At the above location is a prefernces file and I deleted it becasue it had logged all kinds of shit I *did not* want automatically enabled at flight time.

So far I'm running and back to normal - fingers crossed.

Good thinking, dude - there is a lot that goes on in that folder that I distrust extremely. I had forgotten that sometimes, just blitzing that whole folder gives FG a change to set itself up anew.

My fingers are also crossed.

Yes...I learned this lesson about 5 years ago and it's a head slapping moment for me. Should have done this days/weeks ago - somewhere in a game crash this file saved all kinds of stupid shit that it has been reloading every session.

Not sure how it has affected the Python Script gathering TerraSync but I'm convinced they are linked. we'll find out later.

I've noticed that with the latest 2018.2.1 you need to disable the scenery download
from the in game menu. The launcher just isn't doing it for me...

Prior to delecting the above file I was not getting F10/File/Scenery download at all. It stopped working a few days ago/weeks ago and I didn;t worry about it because I was downloading/installing TerraSync via Python. Apparently that symptom was pointing to an underlying bug or setting that was disabling my ability to fly at all if TerraSync was not available.

My Python script is hanging at the same Airport Process - I suspect some person is "modifying" that or fucking with it on the TerraSync Server. I suspect a lot of the folks who are "improving" TerraSync are overloading it with demands or uploading tremendous amounts of unnecessary bling and tarting shit up causing issues.

But I have no proof of that just an idea.

I reckon a good first step for Porcy is to try the same approach - IIRC, you can delete all the contents of AppData\Roaming\flightgear.org and it will just recreate the bits it needs, but I'd maybe get a second opinion before trying it... it might be worth just getting rid of the config file VooDoo mentioned as a first first step...

I recon 90% the issues are generated by the new launcher. I use the old FGrun and mostly things are ok

My crashes are almost always somewhere in OpenSceneGraph - usually the system removing reference to an object that is still in use (in scenery)

I have a full mirror of Terrasync, and I have an idea about an alternative distribution method - Resilio Sync (used to be called bittorrent sync)

I already run it on my NAS (that holds the mirror) - I could setup a read only share & give people the key - it would need a few people to setup a big enough swarm so that my home line doesn't just get swamped (it may still do...)

anyway - just a thought

regarding scenery downloading not being able to be disabled from the launcher - it's a known bug & a fix is coming

from the mailing list (James):

This is one of those times when the launcher and the built-in auto-save act weirdly, I’ll make the launcher aggressively disable the option, so that the in-sim UI always matches what was set in the launcher.

(The failure is, the launcher doesn’t set ‘—enable-terrasync’, since its setting is ‘off’, BUT it was previously enabled and hence saved by autosave.xml when FG exits, so inside the sim, it’s still turned on. The launcher needs to pass —disable-terrasync in this case to force it off)

Mirror mirror on the NAS, give me the scenery enrougue has...

I might be up for helping out with this little experiment, I have a 3TB NAS and a fast fibre internet connection...

Algy - what sort of NAS do you have? It may by already supported by resilio - see

www.resilio.com/platforms/other-devices/

I use the free version/plan, so only able to sync whole folders which is fine for what I do - it can set an upload rate as well

The only thing I do when setting up a share is turn off the 'Store deleted files in folder archive' option

It looks like my NAS isn't supported - it's a Western Digital MyCloud, but just MyCloud without any other designation after it. I figure it must be the entry level version :(

It does have the ability to do HTTP downloads though, it seems...

In any case you don't have to have a NAS - you can just grab the desktop version of resilio sync & use that to save wherever is best (even the NAS via a share if you want)

I run the free version of resilio on my Mac & I use it on Windows to regularly backup my work laptop (we have no backup facilities for work machines would you believe it)

Yep, that's her :)

OK, I'll look into Resilio later today...

Algy I sent you a PM with the key for the read-only share
