Wow.exe Memory Leak?- CPU Pegged 99%



#0 - Oct. 17, 2008, 11:05 a.m.



After installing the patch a few days ago on my machine and my wifes machine (Specs are below) we've started finding the machines running very slow when we try to minimize the game and look something up on Thottbot.com etc.. A look at the task manager on each system under processes shows Wow.exe using 99% of the CPU. It shouldn't be necessary for the game to use that kind of CPU.

So we decided to install the patch on our newer gaming laptop which is a little more beefy and see how that went, same thing. Wow.exe pegged the CPU at 100% while logged in walking around.

Before you even ask..

1. No I do not use add-ons.
2. Nothing else has been installed on these computers besides the patch.
3. Yes, pre patch they ran smooth as butter.


Testing the CPU from start to close..

- Launcher.exe - Was: 0% after load.
- Nothing wrong here.

- Wow.exe - Login Screen Was: 30 - 33% solid.
- Background AVI with proto dragon?

-Wow.exe - Logged In Was: 00 - 02%
-Looking at character list for realm.

- Wow.exe - Enter World Was: 93 - 99% solid
-No movement, just standing in Stormwind. Pegged.

Memory leak getting worse every patch!

I can’t play more than 1/2 hour before the game has eaten up all 32 GB of RAM on my machine and crashes with an out of memory error. This leak has been around for over a year and continues to get worse with every patch.

Should we assume you are not looking at it and don’t care about fixing it?

I play all day running multiple copies of wow at once. I’ve never encountered this. Sounds like you have an addon that’s leaking memory. Blizzard enabled the ability to see more information about your addons in the latest patch. Check it out.

Same, the only leak I’ve encountered in the past was the crafting memory leak, which actually appears to be fixed with 11.1

Thanks for the info, but I don’t use addons.

This is a hardware or software issue on your end. Question for yah. how many sticks of ram do you have and what is the ram exactly?

I have figured out how to easily get the game to use up all my RAM:

There is a world quest near dornagal that requires you to kill a bunch of nerubians an

I've been playing World of Warcraft 3.3.5a with wine for a while, and yesterday, for the first time ever I got a crash message saying the program ran out of memory. I went and checked and other WoW processes were consuming up to 1100M of memory, for reference: WoW under windows hardly ever goes above 400M. I went ahead and made some tests

1. Before login, the process consumes about 170M in wine and 110M in windows
2. On both systems it nearly doubles after login
3. In wine, however, logging out and back on, or reloading the interface increases the memory usage by 5-10M every time
4. There isn't any periodical drecrease on memory usage under wine (it somewhat fluctuates under windows)

I measured the resident memory under wine (as reported in number of pages in /proc/.../statm) every 0.5s and it was quite conclusive

I've observed this leak in two computers, both running Arch with amd gpus, one with wine 2.0 and the other 1.9, same results.
The tests under windows and wine ran with the same wow settiings, namely low graphic settings and using the opengl gxApi

I might have to compile wine with valgrind later, but in the meantime, is there any way to spot where the l
