Cities.exe caused an Access Violation (0xc0000005)

[ArchArtas]

So the game just randomly goes "oops crash", previously it was just crashing from going out of ram (16 F***ng GB OF RAM) but I turned off Traffic++ and traffic manager and it went down to 13gb. Even though I've got around 700 assets, that looks like an memory leak to me or some funny asset being fat as hell. Anyone got some ideas for fix?

A simple mistake people sometimes make is launching the game, without first checking for free disk space. if you have low space, and game starts filling it up via page file, you'll crash. I have 16GB of ram, and this game fills it up, and starts using disk space, so it needs room there. I find that if I have less than 16GB of free space, it'll crash during loading. once the game is running I can see that my disk has actually filled up a lot.

[Someone™]

Does it still matter if the drives that I don't have the game installed on don't have much space?

[nuttapillar]

I don't think so. Unless Windows uses them for pagefile/virtual memory. But I'm pretty sure it will just use your system (C:) drive for that.

[Someone™]

Cities Skylines is installed on my (D:) drive

[nuttapillar]

Well, just have at least 16gb free on each drive to be sure. I wouldn't worry about any external drives though.

[Someone™]

I have 64 GB allocated on my (D:) drive which Cities: Skylines is installed on and I still get crashes from lack of memory??? (There's still over 1TB left on it)

[nuttapillar]

have you got a lot of free space on C drive?

[Someone™]

No, about 1G, but it's tiny so there's not that much that I can do about it without uninstalling a heap of stuff that I still use.

[nuttapillar]

well 1GB of space on your C drive is likely the reason for it crashing. It fills up while loading and your game crashes. You gotta clear some room. Try running CCleaner.

[Someone™]

I have CCleaner.
Thanks for the information though! This may really help me.

[Someone™]

Ok, went over to my other profile and found 11GB of captures (Jeez) and now I have a fair amount of free space.

Edit: Yep, looks like the problems that I've been experiencing for the last few months are fixed. Thanks a heap, Nuttapillar!

if you check the output log you can see it its a memory problem or a mod

i got this

i just need to free more space for the page file

[MarkJohnson]

It's a workshop issue. Just too much subscribed to and you filled up your RAM and Virtual memory (pagefile) and got the allocation error. i.e. there is no more memory to allocate.

Three simple solutions.

1. Add More RAM

2. Free up RAM - Unsubscribe some workshop/windows apps

3. Turn off auto-pagefile in windows. It either is flakey or limits pagefile size. Manually set your pagefile to triple your system RAM for Initial size and maximum size. If you have 8GB then set pagefile to 24000mb (24GB) and you'll have 32GB RAM total.

Microsoft recommends a maximum of 3 times system RAM, but I've set it to 4 times RAM with out issues before.

[nuttapillar]

And regarding pagefile, don't make the mistake I did, and have your hard drive too full to actually fit the page file lol. That will crash it too.
