Memory leak leading to crash

Technical Support
1

When I visit a lot of places in adventure mode, I see the memory usage of the Diablo 3 process going up and up and up. It will eventually lead to a hard crash.

In my D3Debug.txt file, I can see at the end:

2021.01.28 11:10:52.724797700 XLocalHeap 00000219FBAE1C70: Nodes used: 157605, Memory used: 787442848/805306368, Wasted by nodes header: 5235232, Biggest contiguous free block: 7627104, Biggest contiguous allocated block: 67108864
2021.01.28 11:10:52.732499200 XLocalHeap 0000021986BAB080: Nodes used: 571509, Memory used: 67108864/67108864, Wasted by nodes header: 18411520, Biggest contiguous free block: 0, Biggest contiguous allocated block: 2016

Please note the “Biggest contiguous free block: 0” part.
It generated a dump file on crash (App-0.dmp), but I don’t know if/where I should send it.

I have 32gb of ram, i7 10700k, running 64 bits version of D3.

I know this was a looooong time ago but this needs more attention. I’ve found on my system (Win 10, 32GB ram, 8700K) Diablo seems to reliably crash once it reaches ~5.4GB of memory. Each map visited whether by visiting waypoints or entering new floors in GR adds 100-200MB of ram and is not cleared until I return to the game lobby.

Seeing the same issue on a 64GB system. Game crashes to desktop after a few hours of playtime. Inspecting the D3 process in task manager shows it using every bit of memory on my system which is insane.

I’m also seeing this issue.
