Thanks for the report and the log files. The log files say it was an out-of-memory error (there are a few other messages in there but they're the sort we tend to see when the game has run out of memory). This is different than the other out-of-memory situations we've seen, though, because the errors are reporting that the managed heap was at less than 300MB and it generally can grow to about 800MB before it dies. Further into the logs I found that it claims the physical machine this was running on only had 1 GB of RAM. Of course, the published system requirements for the game say 1 GB (2GB recommended) but in order for that work that's the amount of memory that has to be _available_ to the game; it is likely that your OS and other programs running are holding on to at least 200 to 300. In theory if it runs out of physical memory it's supposed to use the swapfile for virtual memory, but in practice I've seen that generate tremendous slowdown at best and instability (in the form of reluctance to grant more memory) at worst. Anyway, questions so I can better figure out what's going on here: 1) Does this machine really only have 1 GB of RAM? 2) How long had the game been running at that point? Thanks :) |

1) The system has 4GB of RAM. 2) The game had just started. |
|
|
Then something is _very_ odd, because the error.log in the attached zip says: 1024 MB physical memory [1024 MB free]. 2048 MB paging file [1024 MB free]. 2048 MB user address space [110 MB free]. Aside from some kind of VM I don't know how it could even get the amount of RAM wrong. |

It's not VM. |

A few notes/questions: - It's possible that this is actually just a corrupt install of the game, actually. When that happens all sorts of funkiness happens. If you verify your steam cache that will fix it up back to 1.0 (you won't have to reinstall the expansion, if you have the expansion), and then you can update back to the latest version of the game. - What version of the game are you running, by the way? It doesn't say that in the log file there. I'm assuming the latest beta. - What version of windows is this? By any chance is this windows 8? - The actual error here is "Attempt to access invalid address." That is often tied to out of memory exceptions, and the fact that the actual physical RAM is misreported is really strange, but it could also be something like another program interfering with memory allocations for the game. Antivirus, for instance. - In this case I notice that you're using Avast antivirus (it's one of the loaded modules listed in the crash dump). Looking at the crash dump you provided, there really does not seem to be anything else a chance of interfering with the program execution in the way that I mentioned in the above item. You might try temporarily disabling Avast and seeing if that solves the issue. If so, we can see what we can do from there. - In the error.log file, it notes the DirectX version as having a ProdVer of 6.1.7600.16385. when I google this I get very few results, most of them problematic: https://www.google.com/search?q=directx+6.1.7600.16385 Is there a possibility you don't have the latest version of DirectX installed? Hope that helps! |

Oh, I should have looked at our specific log files. This is looking more and more like a corrupt install, or possibly a bug in 5.059, which I see you are on. There are ridiculous numbers of exception in AIErrors.txt: System.NullReferenceException: Object reference not set to an instance of an object at AITactics.CarrierCreationChecks () [0x00000] in <filename unknown>:0 at AILoop.RunAILoop () [0x00000] in <filename unknown>:0 Which culminate in this: System.ApplicationException: The thread does not have the writer lock. at System.Threading.ReaderWriterLock.ReleaseWriterLock () [0x00000] in <filename unknown>:0 at AILoop.ReleaseAIUnitUpdates (Boolean IsForWrite) [0x00000] in <filename unknown>:0 at AILoop.RunAILoop () [0x00000] in <filename unknown>:0 Which could very much cause an access violation between threads looking at given data. Keith, you may want to check into AITactics.CarrierCreationChecks and see what you can see about null reference exceptions. That would be more likely before PrimalPhantom goes off on a long chase of other potential issues. |

Last note, I see there are also some of these: System.OutOfMemoryException: Out of memory at (wrapper managed-to-native) object:__icall_wrapper_mono_string_alloc (intptr) at (wrapper managed-to-native) string:InternalAllocateStr (int) at System.Text.StringBuilder..ctor (System.String value, Int32 startIndex, Int32 length, Int32 capacity, Int32 maxCapacity) [0x00000] So that's where Keith was pulling the out of memory exception note from. However, looking at the above errors I'm thinking this may actually be a downstream error from some sort of thread clash between the AI thread which is having a null reference exception rather than it being a literal out of memory exception directly. |
|
|
I already checked AITactics.CarrierCreationChecks when I saw those errors but that method has not changed in a long time and as far as I could tell there could only be nulls if the AI Loop's player or planet collections had nulls in them. So I figured that there had been an out-of-memory exception while it was trying to initialize those, leaving nulls in them. |
|
|
Hmmm. Then a corrupt install is again looking more and more likely. |
|
|
What version of the game are you running, by the way? 5.059 What version of windows is this? By any chance is this windows 8? Windows 7 latest version of DirectX installed? 11 |
|
|
This game uses DirectX9, which I believe is included in DX11. However, there's a chance that all the latest updates to DX9 aren't in DX11 or something. Still, my money is on corrupt install at the moment. |
|
|
Mine too, the main reason being the lack of other reports where this has happened :) |
|
|
Steam states the cache is valid. |
|
|
That's... particularly odd. Because if you're on the latest beta, then by definition the cache should not be valid. Even if there was nothing else horrible going on, it should have reverted you to 5.000 to my recollection. |
|
|
Just re-validated the cache again and 69 files needed to be downloaded. |
|
|
I can confirm that 'Verify Steam Cache' will revert your AI War install to version 5.000. I moved the physical drive my steam install was on last month and had to do that to AI War and I had to reinstall all the betas to get back to the latest version. |
|
|
Yea, I just now did a validate-cache on my 5.059 steam copy to test it, and it said 68 files needed to be redownloaded. Maybe that extra 1 in that 69 is the problem ;) |
