Strange things happen to me at Origin lately. The client just crashes.

The end of debug log:

And dmesg shows:

I'm currently supposed to be standing in front of Felfa's bicycle store in origin, and i crash at once when the client connects. I cannot even execute /home or press the home button to get out. I cannot play basically.

What version of minetest client are you using?

Posted: **Mon Feb 10, 2020 19:27**

5.1.1-ppa0~ubuntu16.04.1

Tried with both intel and nvidia GPUs. No difference.

Sounds like https://github.com/minetest/minetest/issues/7015 to me...

Posted: **Mon Feb 10, 2020 19:35**

Hmm, looks really weird. Could it be caused by the large amount of bicycles in that area?

Should I try to tp you away from Origin?

I don't know. My debug shows nothing useful. Maybe it's bikes. Maybe something else. But it looks like something which is a mesh. We have a lot of those actually. And if I found the exact bug report, then it's not even about quantity, but about quality. One broken mesh is enough.

If you can tp me in my absence, please do so. I cannot do anything myself, and I tried basically everything. There is no time to even ctrl+V a command.

Posted: **Mon Feb 10, 2020 19:38**

I can try to tp you before you time out...

Also an option, yes. Thank you for suggestion.

So far it appeared that it's indeed possible to teleport the player between the crash of his client and timeout.

Also I took another laptop, and didn't experience this issue (it has a different distro and intel gpu, but same client version).

The problem has been reproduced by Luna-HD. I will ask him what hardware and os he is using.

Posted: **Sat Feb 22, 2020 14:28**

Luna-HD is on OSX, seemingly with Nvidia graphics.

For future reference: This happens when someone is currently saving a page on the wiki. The relevant line is:

Code: Select all

Error: 5 database is locked

MediaWiki doesn't handle the error very gracefully for whatever reason. Don't worry if you're trying to save a page. Your changes aren't lost, just hit F5 after a little while to attempt the save again.

My network access is a bit restricted right now, connecting via mobile only for 1-2 weeks and connecting to the server via mobile network is not the best Idea...

We are nouw the Free Toilet Paper Server, in an attempt to use the coronavirus pandemic to attract more players.

Posted: **Fri Jun 19, 2020 22:23**

I banned on this server. It says the Expires is Fri 17 Jul 2020 11:46:34 AM CEST, but the time now is Sat 20 Jul 2020 06:22 HKT (Sat 20 Jul 2020 00:22 CEST), why I still can't enter the server?

Posted: **Thu Jun 25, 2020 18:28**

it is currently june, not july.

Posted: **Wed Sep 02, 2020 16:47**

The server seems to be unstable after the upgrade to 5.2. I was on at 16:30ish UTC today and it was empty, which is far from usual. The server crashed shortly after I joined then again 10ish minutes after that.

gpcf: this also came up in the advtrains thread but I sent mail from gmail to hemiptera recently and it never arrived. I suggest you investigate what hlqkj was talking about.

Posted: **Wed Sep 09, 2020 09:32**

The instability problems seem to be mostly solved, they were related to objects being accessed after being deleted. One of the mysterious "hard crash" segfault bugs also seems to have been solved, however, there's a second one I discovered through use of gdb.

Was it by coincidence related to "the getyaw() trick"?

I genuinely LOVE this server and the community! <3

Posted: **Thu Mar 04, 2021 16:43**

Yes this server has so a nice Minetest & Linux & Trains community, sad that there is no manual to build a railway system, if a manual exists please tell me (I don't mean interlocking)

I see that someone should write a "How to set up a rail system using advtrains" page on WikiHow (no, I'm joking).

IMO "building a rail system" covers more than you might think, some of which may not be related to construction itself. Some of the factors to take into consideration include:

The purpose of the system (passenger and/or freight transportation)
Signaling (e.g. LuaATC and/or interlocking)
Construction quality
Signs and documentation (e.g. wiki, passenger information system)
Connection to existing tracks
Right of way (when building a rail line through someone else's area)

... I am not sure if these can be (easily) covered in a single manual.

Posted: **Sat Mar 06, 2021 12:31**

Thanks for your answer, I was now able to set up and Interlocking system with trains not crashing, I think now there is an good manual to make things like this but it needs to be translated, I think I’ll do this in near future! (To German)

Posted: **Sat Mar 06, 2021 21:12**

For the basics, you might look at the advtrains wiki at https://advtrains.de/wiki . Our server wiki also has some good documentation (https://wiki.linux-forks.de/mediawiki/i ... Styleguide).

Otherwise, the best approach is probably "learning by doing". You can look at how the railway systems are made on the server and then try to build your own railway. If you have trouble, you can always ask other players for help.

There's also that ATC learning course at Spawn University.
