I'm also seeing this on my Nexus 4. Except here, gstreamer hangs and makes the process unkillable.
Here is a bit of trace from our code: thumbnailer-service: [06:53:02.902] timeout, state = 2 thumbnailer-service: [06:53:02.902] killing process 12806 thumbnailer-service: [06:53:02.902] calling waitpid for process 12806 thumbnailer-service: [06:53:31.900] waitpid for process 12806 returned This happens when a timer fires. If gstreamer doesn't complete within 10 seconds, we kill the process. (Each video thumbnail is extracted in a separate process, so we can recover from gstreamer crashes and hangs.) However, take a look at the time stamps. We sent a SIGKILL at 53.02 and immediately called waitpid(). But waitpid() does not return until 29 seconds later. This strongly suggests a kernel problem. (At least as far as I know, the only way for SIGKILL to not kill a process is if the process is asleep in the kernel at uninterruptible priority.) ** Changed in: gstreamer0.10 (Ubuntu) Importance: High => Critical -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1466273 Title: gstreamer fails intermittently To manage notifications about this bug go to: https://bugs.launchpad.net/thumbnailer/+bug/1466273/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
