Steps To Reproduce

(Please read additional information before.)

  1. Install AllInArmaTerrainPack ( and SMD Sahrani A3 (
  2. Host new multiplayer session. Load and start test mission (mission included).
  3. Press 'Esc' and switch to camera. Set speed to 1.
  4. Fly low above the road to Corazol (holding Shift key).
  5. Fly through Corazol above the road from east to west and out of the city.
  6. Stop camera mode. Abort the mission.
  7. Select another island (Altis) in 'choose mission' window.
  8. Select "Start 2D editor..." and start editor on Altis.
  9. Exit editor without saving.
  10. Switch back to SMD Sahrani A3 island to test mission and try to reproduce again from step 2. The error already must occur.

The error may occur when:

  1. You fly through Corazol (step 5).
  2. You switch to another island (step 7).
  3. You switch back to test mission (step 10).
Additional Information

We made a lot of tests to find out the cause, and here the results:

  1. I can reproduce this error with 100% success. And I'm ready to give you any logs or other info to fix this issue.
  2. It's not related to my software or hardware because the same issue happens to all people from our community. And we did a lot of special tests with 6-8 people in many multiplayer sessions and crash happens for all of them.
  3. The crash happens on clients, on host (non dedicated) and on dedicated server. We tried different scenarios.
  4. The crash is related to SMD Sahrani A3 island, but before 1.50 it worked perfect.
  5. I tried to remove all buildings, roads, vegetations, rocks and all other objects from this island. It doesn't help. I had only terrain with ground texture and nothing else but game was crashed anyway.
  6. It looks like error happens when game is trying to release something from memory. Because it can happen when you switch to another island, or flying through some area, or when you reconnect to the same session (go to lobby and then back to game).
  7. The error messages are varied. Some times it says 'memory could not be written'. Some times it says 'memory could not be read'. Some times it crashes without any message. But always it related with access to low memory addresses.
  8. I tried the latest dev build (2015-10-07) and it doesn't help.
  9. I tried different memory allocators and different strtup options it doesn't help.
  10. I tried legacy 1.50 build and the error is already there. I can't try legacy 1.48 build because it's not accessible.

If SMD Sahrani A3 island is part of All In Arma (Standalone or Terain Pack), this is the cause. 1.50 and 1.52 is not compatible with AIA.

Agree with Pershing, Wrong place for this ticket. If you wanna more compatible terrain pack from A2, wait for update from CUP_terrains.

Do they (CUP team) already know what the cause and how to fix this issue?

Kaban added a comment.Oct 12 2015, 2:20 AM

Ok. You don't have any useful info about this issue. And CUP team even doesn't know about this issue. And CUP terrains release is not planned yet. And you advised us to wait for CUP update, did you?

May be it would be better if BI said what cause this issue and how to fix it. And why it was working before 1.50 and since 1.50 it doesn't. And then I will go to CUP team and talk to them about this issue or fix it with my own.

I have done a lot of work to find out the cause of this issue. I tried a lot of things. And I suspect that it's related to memory allocation. How CUP team can fix memory allocation? I just want to hear a word from BI about this issue.

You just have writed "SMD sahrani related" (why now you are seeing fault in allocator - try diferent instead of waiting)!

CUP have released their version

AIA is Officially not supported in 1.50 and 1.52 READ their official statement of forum

Anything more? Ahh "usefull info" are on other tickets ABOUT THE SAME BUG - use search option instead making mad

I'm sorry for making mad. My bad. I didn't want to be rude.

You talked about incompatibility AiA and CUP updates but the main question was what the reason of that incompatibility and how to fix it.

Thank you for link to CUP TP Release Candidate. I made several tests with it. And issue looks to be fixed with CUP TP.

I tried to replace AiA TP to CUP TP, but it didn't help. The old SMD Sahrani A3 island crashes the game anyway. So the cause is not in AiA but in island itself.

But with new CUP Sahrani island I can't reproduce this issue. So it looks like the issue was fixed. We need to make more tests. But for now the ticket might be closed.

I keep hitting it after removing all mods deleting arma 3 and reinstalling 1.52. I launch into a map, "King of the Hill", and others and withing 3-4 mins the game crashes with this error. I'm running on windows 8.1 64 bit. In my opinion this problem increased with the release of 1.52. I attached my latest crash dump. I am not running any mods when this hits.

I also tested with Arma 3 build 1.53 and got the same result 2 minutes after playing the map. Uploaded the crash dump for that as well.
