Massive memory leak after closing stats window when OpenGL rendering enabled. Was: game crash and system hang - randomly

[RJ]

When I play winelands (campaign) game (and os) randomly hangs with no response from mouse and keybord. After system and game hang I can only do hard reset. Computer works very stable on any other app / game.
More info about system:
OS: BridgeLinux (based on ArchLinux)
Kernel: Linux 3.3.7-1-ARCH #1 SMP PREEMPT Mon May 21 22:39:59 UTC 2012 i686 GNU/Linux
Grafic drivers: nvidia 295.53
WideLands version: build-17(Relase) (from official arch repo), lang: polish, 1024x768px, Windowed mode, music off; opengl on
Every crash happen on campaign (last on atlantis 1st mission after about 2h).
Unfortunatelly I haven't last errors from ~/.xsession-errors, but yesterday when I browse this file, ends with something like that:
TI(187486): destination disappeared or economy mismatch -> fail
TI(187420): destination disappeared or economy mismatch -> fail
TI(187402): destination disappeared or economy mismatch -> fail
TI(187978): destination disappeared or economy mismatch -> fail
TW(154753): destination disappeared or economy mismatch -> fail

Issiue is very annoying, game is unplayable.
P.S. Sorry for my bad english.

Is this only in fullscreen or also in Window Mode? Does OpenGL
(options->advanced->OpenGL) change anything? This is the first time I
hear about widelands being unstable, therefore I wonder if something
else might be involved here.

I have noticed similar behaviour. What happens in my case is this:

- I play barbarians, any multiplayer map over LAN
- I open statistics window
- I watch all "general" statistics graphs
- I close the statistics window
- THEN (only *after* I have *closed* the statistics window), widelands embarks on a memory rampage, freezing my OS when it fills all available RAM.

Before closing the OS, it uses a constant amount of RAM, typically around 700 MB.

I use build 17 on an up-to-date Arch linux distribution. The problem does NOT occur if I disable opengl rendering from the command line.

Extra info: I use the xmonad window manager under XFCE 4.10.

[Michiel Brentjens (m-a-brentjens)]

And I always run full screen. Don't know yet what happens in windowed mode.

[LaunchPeter (launchpeter)]

I have simmilar problem. If it is not the same, I can open a seperate bug.

In my case the crashes seem to happen randomly (not connected with the stats windows). Happens in PvC games as well as in the campaign.

I get the message
destination disappeared or economy mismatch -> fail
and then the whole system hangs. Only a restart of the computer helps.

It happend with the last few versions from the Ubuntu-PPA. Lastly with
Widelands-bzr6473[trunk](Release)

Some system information:
Ubuntu 12.10
Linux 3.5.0-21-generic x86_64
XFCE 4.10
Nvidia-drivers 304.43
Windowed mode, music off; opengl off

[SirVer (sirver)]

a reliable way to reproduce this would be most welcome - otherwise this bug will be hard to track down. Savegames sometimes prior to the occurence might also help as long as this happens sometime. Note the autosave feature which might yield a suitable game just after a crash.

May be related to bug 1096632

Can you try to re-create the problem with the latest trunk revision? The bug I suffered, which seemed similar, is no longer affecting the game when playing revision 6567.

three month since comment #8

Anyone can reproduce the bug? If not, I guess we can close this bug report

[SirVer (sirver)]

Released in build-18 rc1.
