I've been battling a hang (deadlock) in OpenGL for the past week. I've finally realized that the system hangs after the garbage collector runs. Here is an example from LogCat:
02-16 08:49:32.609: INFO/ActivityManager(98): Displayed activity com.southernstars.skysafari/.SkySafariActivity: 2219 ms (total 2219 ms) 02-16 08:49:37.369: DEBUG/dalvikvm(1863): GC_FOR_MALLOC freed 4144 objects / 387544 bytes in 46ms 02-16 08:49:37.389: ERROR/Adreno200-ES20(1863): gsl_device_waittimestamp failed in rb_timestamp_wait_on_timestamp 02-16 08:49:38.516: WARN/SharedBufferStack(1863): waitForCondition(LockCondition) timed out (identity=157, status=0). CPU may be pegged. trying again. ... ... Anytime the LogCat shows a GC_FOR_MALLOC or a GC_EXTERNAL_ALLOC, the app hangs with OpenGL in this LockCondition. It appears that GC_EXPLICT, for the most part, does not cause a problem (maybe these are smaller allocs, I don't know). Searching the internet, it seems that people are reporting things like this on the HTC phones. Usually they say the problem is very sporadic and hard to reproduce. I can reproduce it easily by simply putting a System.gc() call into my application flow or by doing something that allocates a chunk of memory forcing the GC to run. I have this problem on an HTC Evo. My development partner has a different phone and is not seeing this. I'm totally at a loss what to do next. Has anyone seen anything like this or have a plausible explanation for what is going on? Is there any way it could be something unusual we are doing in the app? Or is it just a bug in the HTC system or drivers? Thanks for any help. -- Bill Tschumy Otherwise -- Longmont, CO http://www.otherwise.com -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
