Can you fix it?

britzl · August 13, 2019, 10:13am

Can you reproduce it?

filazopovich · August 13, 2019, 10:29am

I don’t have stable steps to reproduce.

britzl · August 13, 2019, 1:24pm

It looks like it happens when the engine is being shut down, perhaps while an HTTP request is in progress. @Mathias_Westerdahl any input?

filazopovich · August 13, 2019, 9:14pm

I think that crash is occurred after ‘reboot’ message if any http connection is active. We often use http. And we use ‘reboot’ message in special cases.

britzl · August 13, 2019, 9:53pm

Ah, thanks, that might be a lead.

jhonny.goransson · August 19, 2019, 10:09am

I think (hope) that this has already been fixed in 1.2.160 coming out today. But for the sake of it, let’s look at what we have at the moment:

Could you provide me with your .so file that’s causing the issue? You can share it with me at jhonny.goransson@king.com or at our slack
Have you noticed the same behaviour on other platforms than Android?

Meanwhile I’m gonna see if I can fiddle with rebooting during http requests and see if there’s any issues there. I’m hopeful that it’s been fixed already but you never know…

AGulev · September 3, 2019, 8:02am

Solved in 1.2.161

filazopovich · October 1, 2019, 11:03am

Crash rate is decreased from ~1% to 0.02% after fix. Thank you!

britzl · October 1, 2019, 11:52am

This is very good to hear! Thank you for getting back to us and confirming that it is fixed!
