Bug [Unity 2019.2.17f1] [Android] Particle systems Crash

Hi, I am getting a lot of these crashes on Android, using Unity 2019.2.17f1.

Seems to be something related to particle systems and memory. What could cause this?

The scenes are mostly single image with a particle system attached to touch movement

Short backtrace:

libc.so (tgkill+8)

Hello @tigerss, we experience also Android crashes because of particle systems. You can review this thread:
https://forum.unity.com/threads/and...ith-ring-buffer-mode-loop-and-trails.1192972/

Maybe some of the workarounds presented there will help you.

 

Hi @Soulside, thank you for the info! I hope someone from Unity helps with this, is there any way to get in contact with Unity on this one?

What should I do with this thread? Maybe close it and continue discussion in your thread?
