[16.35] intel_do_flush_locked failed: No space left on...

[wolandmaster]

Recently the game very often crash with the following error message:

Code: Select all

1726.558 Info AppManager.cpp:260: Saving to _autosave3 (blocking).
1728.906 Info AppManagerStates.cpp:1642: Saving finished
intel_do_flush_locked failed: No space left on device
intel_do_flush_locked failed: Invalid argument
Segmentation fault

It is usually happens when a automatic save take place, so it is very
annoying that I lose 5 minutes gameplay and have to do the same things again.

I'm using Ubuntu 16.04.4 on Dell Latitude E7440 notebook.

Thanks in advance!

"No space left on device"

Check if your computer has enough disk space to save your game.

Tought that a few version back there was a change that they solved crashing when saving game, while computer had no diskspace. I guess there still an misstake there in the code.

Post a log with crash please.

[Rseding91]

Thanks for the report however the log file doesn't show any crash in it.

[wolandmaster]

The attached log was used/written during the crash
(yes, I also saw that the intel_do_flush_locked lines are missing from
the saved log, that's why added the end of the console output to the first post).

I think it is not related to the disk, it has enough space:

Code: Select all

# df -h
Filesystem                   Size  Used Avail Use% Mounted on
udev                         7.8G     0  7.8G   0% /dev

Looking online it looks like that's a driver error with the OS you're using and outside of anything we can control.

[wolandmaster]

Hmm, OK, but this crash happens for roughly a month ago.
Do you think that an ubuntu (intel driver) update caused the problem?

Based on the dpkg log, the last intel related install was on last august:

Code: Select all

# zgrep -iw intel /var/log/dpkg.log*
/var/log/dpkg.log.2.gz:2017-08-01 11:22:42 install intel-gpu-tools:amd64 <none> 1.14-1
/var/log/dpkg.log.2.gz:2017-08-01 11:24:29 install xserver-xorg-video-intel-hwe-16.04:amd64 <none> 2:2.99.917+git20170309-0ubuntu1~16.04.1

You're getting ENOSPC which means some resource is exhausted. The default error text says no space left on device but ENOSPC can also happen when any other resource is exhausted.

Usually a developer with source code can tell you what resource was exhausted by seeing which syscall failed.

Meanwhile check the output of the ulimit command for unnecessary limits and also run "df -i" to see if you're short of inodes.

[kitcat]

Apparently, the Intel driver fails with ENOSPC if there are too many textures bound/attached. It is not a disk space or file limit problem.

[wolandmaster]

Whats next? Should I change a configuration parameter? or is it a bug?

[posila]

It's a bug in your graphics driver.

It looks like the driver crashes when the game is creating screenshot for preview image for save - if it didn't crash and produced "GL_OUT_OF_MEMORY" error instead (or some other error), the game would not crash as screenshot is not essentiel for the save.

You can work around the problem by reducing how much texture resources the game uses - enable "Low quality sprite rotation" or reduce "Sprite quality" to Normal.

[wolandmaster]

It is crashing with enabled "Low quality sprite rotation" as well:

It is crashed with normal Sprite quality and enabled Low quality sprite rotation.
