I'm having similar issues during world gen on Debian Jessie. The generator succeeds in pocket sized worlds but hangs on anything larger. I'm running the game in text mode. I've waited around half an hour, and the generator doesn't seem to proceed further. One CPU core is constantly at 100% usage.

The server in question:

Can confirm issue is appearing on Mac OSX :

Darwin 13.4.0 Darwin Kernel Version 13.4.0: Wed Mar 18 16:20:14 PDT 2015; root:xnu-2422.115.14~1/RELEASE_X86_64 x86_64

I also get these warnings on startup, but they seem more pedantic than actually indicative of a problem:

Ubuntu 14.04 - same thing; blocked. Was able to get past this by setting number of civilizations to 0 - which creates quite a boring world.

"Placing civilizations" seems to be the point of all freezes reported so far, so I'm retitling this report.

It's freezing for me as well, Mint 17.2. It seems that only Linux/OSX users are having this issue.

System Monitor lists the Dwarf Fortress process as "sleeping", if that's any help.

Toady said he managed to reproduce it a couple times, so it might not be platform-specific, but it's also not reliably reproducible with certain seeds.

Confirmed from me too, also on Ubuntu 14.04. Only way to get out of it is to use kill -9, and that's brutal to use.

Freezing for me also, but on Windows 7 64bit.

Tried to generate 3 large worlds, not in advanced gen. 2 froze on "Placing civilizations", the other one crashed generating history at approx. year 360.

DF 42.01

Note: All generation settings were set to the right most option (My preference), so if it is related to the No. of Civilizations, then that might explain why it has happened to me frequently.

Edit: Just happened again. I have yet to successfully generate a world with these settings. There a log or something somewhere I can link?

However, the first attempt with civs set for normal seems to be working fine (Going through age generation right now) (Nevermind, it locked up generating year 250)

The freezing with civ generation seems to happen frequently while generating civs in mountains, and on top of rivers. In my experience, with about 6 or 7 of my attempts meeting those conditions.



Began generating worlds with normal settings (3333333)
First generated fine, second locked up 147 years into history gen, third generated fine.

Not sure if it is is related, but when I attempted to begin adventurer mode in the first of those successful normal worlds (Seed UMeOsGsCEyQC0i8wOmEo), the game immediately crashed in the Updating World screen (Crashed, not just froze).
Here is the error log from Windows Event Viewer:

So might the commonality be 64-bit systems then, instead of Linux/OSX as I assumed before (and was obviously wrong with)?

Tried generating new worlds with default parameters 16 times, all failures. Usually got to around mid-30s civilisations to be placed before hanging.

Running linux mint 17.2 running on Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz.

Linux ada 3.16.0-38-generic 00000520000014:0000014.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I was able to replicate this bug on 6 of 6 tries with the following procedure:
1. Launch DF
2. Select "Design New world with Advanced Parameters"
3. Press 'ESC' at warning screen
4. Press 's' to set seed
5. Enter a seed of "1"
6. Press 'Enter' to commence generation, press 'y' in response to pop up.

Freezes occurred on Placing Civs at indicator value of 16, 7, 29, 16, 29, and 24.

I've been able to reproduce this issue regardless of world size, number of civilizations, and so on. I've tried the custom parameter worlds in addition to the "vanilla" ones. It reliably crashes anywhere between placing 2 to 30 civilizations. Only way to kill the process is with SIGKILL ("kill -9"). I'm running 64 bit Ubuntu 15.10 running kernel version 4.2.0-19.

I would post a parameter set, but this affects all worlds I attempt to generate unless I disable civilization generation altogether.

UPDATE: The issue is 100% reproducible with Windows 10 on the same hardware. The program stops responding before it can place up to 30 civilizations (sometimes as few as 2). The hardware in question is an Intel i7 2.80 GHz with 32 GB of RAM.

UPDATE TWO: So, on Windows it looks like I can prevent the freezing if I select "Sparse" for the mineral scarcity setting. It doesn't seem to make much sense why this would work, but every time I try to select "Frequent", I get the freeze. If I don't, the world generates just fine. I've generated up to 160 civilizations on a single world and the result is the same. This workaround does not work under Linux, however. I still get the freeze-up during the civilization placement process regardless of the parameters I choose.

Every case I've found of this has been caused by an uninitialized poetry variable which I've now fixed for next time. Those are usually worse on linux, so hopefully it'll account for all of those too, but all I can do is run it a lot and hope for the best. We can reopen it if there are other cases after the next release.
