Hanging app in shim_glBindFramebuffer() from libMali.so

Bram Stolk over 10 years ago

Hi there,

I have an Android app with 3M+ downloads, and I get frequent 'Application Not Responding' crash reports.

When I examine these, my main thread always hangs waiting for futex in shim_glBindFramebuffer() of libMali.so

What could be causing this call to dead lock?

This is the callstack, identical in all reports. I get 15 reports per day or so.

Hi Bram, I've asked the driver team if there are any known workarounds for affected devices, but they are quite busy at the moment so might take a week or two. Thanks, Chris

Thanks Chris,

Are those android version nrs you speak of?
Google Play dashboard just lists it as 4.2. (I think it may ignore sub versions.)

Here is a list of instances of the last few days.

Galaxy Tab3 is listed a few times, so if you have that one lying around, try that one.

Also of the users that emailed me: some were running stock, some were running a modified image (CM10.1), so it can occur on either.
