end of the story

so i don't know if this helps a bit more, it still seems to be in the underlying system a bit

what i saw and found disturbing though, was the use of malloc together with the obj-c memory management (ofwhich i know nothing)

is it maybe possible, that both don't mix so well, so there has to be another allocation method used in interfacing c code?

Posted: **Wed Feb 08, 2006 12:25 pm**

but being in more peaceful systems generally doesn't trigger this bug, it is more often happening in revolting systems with lots of pirates fighting from what i saw

for example being around ceesxe and leoned normally doesn't trigger this (it does sometimes, but really seldom)

changing my flight route to Ususor and around quickly brought me into this bug though (Ususor having 21 pirate vessels and 3 sun skim pirates at this entry time)

Posted: **Wed Feb 08, 2006 12:33 pm**

Can I just point out that it may be better to collate the consistent errors or problems and report them in one go, or even PM them to giles and/or winston and whoever else, rather than post endless crash logs?

I thought that the usual process was to email crash logs or this sort of thing to the developers?

Posted: **Wed Feb 08, 2006 1:48 pm**

tjwhaynes:
I suspect that for the trace with the bellf()s, the stack was corrupted. bellf() is defined in legacy_random.c; it only calls printf() and randrot_rand() (which is a leaf function). Further investigation shows tha my_glDisable(), which is also on your first stack trace, is never called and the app builds fine with it commented out. It’s quite possible gdb is failing to get a meaningful call frame and is sniffing the stack, which will tend to include junk. (This is speculation based on the behaviour of MACSBug.)

(Hmm. This legacy_random stuff could probably be optimised quite a bit. Not that it’s actually costing a lot of time or anything.)

Any crash in objc_msg_lookup() suggests corrupted memory.

This all suggests a memory stomper. Are you using recent code, i.e. after the fix of the dangling-subentity-pointer bug?

Walker:
The fact that your backtraces of CPU spikes both contain a chain of -[AI foo:] messages supports the current favoured hypothesis. If you could confirm that more samples of CPU spikes are also showing AI activity, it might be helpful… although pasting dozens of logs here for us to look at probably isn’t the best way. ;-)

Possibly we need tools to dump and/or trace AI state; possibly something in the update cycle that times AI for each entity and snitches on ones that think too much.

Posted: **Wed Feb 08, 2006 2:15 pm**

no problem, i will check for AI messages

and i did use svn again ... this time rev 252

i should stay with 1.62-2 i know but i always hope for the bug to be gone

Posted: **Wed Feb 08, 2006 7:40 pm**

after playing hours further without problem it started again, and when i try to get back to the debugger, gdb just segfaults

i'll try another round

This all suggests a memory stomper. Are you using recent code, i.e. after the fix of the dangling-subentity-pointer bug?

This is the autopackage for 1.62 which is a departure for me because I normally track the SVN latest (on my AMD64 box which is currently at the dealers being prodded to work out what has blown).

I'll try to build a proper debug version of oolite. I've debugged other oolite nasties before using gdb with a proper debug build.

Cheers,
Toby Haynes

... in the meantime, I'm restarting the game every 2nd planet I visit, since my PC otherwise runs out of virtual memory when there are many encounters and the kernel kills the oolite task.

Hopy someone finds the bug soon - on the other hand, maybe it's a secret Thargoid plot to get rid of us :->

Posted: **Thu Feb 16, 2006 3:02 am**

Here's a few proper stacks (this time from my AMD64 Ubuntu box which is working again

). It looks like we are deep in the AI - I have no idea whether all these stacks are helping. Let me know if you want me to run with some debug code - normally I run at about 40% cpu usage in oolite so I have plenty of CPU headroom still.

Code: Select all

See the thread in 'Testing and Bug Reports' which has an object dump. The problem definitely starts out in the AI code - I have not yet been able to determine whether it's a problem with Oolite's code or GNUstep. I'm keeping a very open mind about it - although Giles has not encountered it on the Mac, it's one of those annoying bugs that are difficult to recreate and don't always happen (from this thread we see that some people see it after about 10 minutes of gameplay, yet it once took me 14 hours to reproduce it on my hardware, and normally takes me at least a couple of hours to reproduce. For all we know it might happen only once every 100 hours of play on the Mac!)

But this is the nature of anything that's triggered by AI - the AI is somewhat non-deterministic in what it does.
The current suspects for the trigger are: docking AI and wormholes. I've only ever seen it happen with multiple wormholes in the system (I may try and just disable wormholes and re-run the game to eliminate them from my enquiries). Short of sitting at my PC for hours on end, the fastest way I've found of reproducing this is to launch and sit somewhere near the space station (without blocking the entrance, normally I loiter by the witch point beacon).

At the same time I can't discount a bug in GNUstep, so I re-built the GNUstep base shared libraries as a debug build.

I often trade between Ensoreus and Ararus (Galaxy 1) as they are the classic Rich-Industrial/Poor Agricultural close pair for good trading runs. Ararus is an anarchy world and it is there that I have had almost all of the memory consumers wipeouts. I rarely make more than two or three runs to the Ararus station before I hit this bug.

And I'll check out the other thread

Cheers,

ive had this bug too ive been searching for what it sould be ...but im using the 1.65 oolite build is there anything to do to fix it ?

Posted: **Mon Oct 27, 2008 8:44 pm**

I've been playing on 1.71 for quite a while and found it a lot more stable and memory leak free. I play on an old steam powered system, but all the shaders and other high-end stuff is turned off if you don't have the power to support it. Bugs are squashed as the development releases move on, but 1.71 runs much better than 1.65, so definatley worth updating to. Everything that works on 1.65 still works on 1.71 and there's now quite a few OXPs about that require 1.70 or higher.

Posted: **Tue Oct 28, 2008 3:17 am**

so i tried version 1.7 but just cold not get it to run after i installed it...even as root. It seems as though i am stuck with 1.65 in the repositories.. is there any way to fix this issue or maybe some tricks to get 1.7 to initialize? I could try all day but even after installing the libjs.so that it was screaming for it still didnt run and still screamed for the same thing....please help i hate having such an unstable game ....thanks

Oolite Bulletins

Oolite consumes all memory

next one

i am not really sure

hehe

mmh

sry for posting such things

Better gdb traces...

Repeatability

me too!

1.7 so sad
