Smoke Simulation Memory Leak on Linux
Closed, ResolvedPublic


System Information
Ubuntu 17.10 64bit

Blender Version
Broken: Ubuntu 2.79.6 64bit, build 23.9.2018

Worked: Windows 2.79.6 64 bit, build around 6.9.2018
Worked too with 2.79b official builds

Baking Smoke simulation fills RAM and swap file then crashes on linux. Works under windows.

Reproduce: Just bake smoke sim in attached .blend file.



Event Timeline

There is no memory leak detected by ASAN, but can confirm it does take a huge amount of RAM very quickly here (just two or three simulated frames at start of baking are enough to fill up my 10GB free RAM…). Then the simulation is a very heavy one, so no idea (or ways to compare with Windows) here. Have the same results with Debian’s 2.79b package, though.

Under Windows 10 RAM usage stays below 15 GB (around 9-12 if I remember it correctly). In ubuntu 17.10 it never stops filling RAM and swap file. Can't do any further tests though since I'm not at work the next two weeks.

This might be the same as T54287, please try with tomorrow's daily build or a newer version to verify if it's solved.

Tested it with yesterdays build. RAM usage stays below 12 GB on a 32 GB system. It no longer fills up RAM and swap file.

Thank you!
