An easy way to reproduce this (works for me at least):
Install "stallboard" app from the store, run it, play a couple of sounds
and then close it (swipe up/down in the window list) => media-hub-server
starts spinning. This doesn't involve a unity8 crash, so not 100% sure
it's the same problem desc
The spinning futex wait we get in the strace:
2391 futex(0x1072a70, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN
(Resource temporarily unavailable)
Comes from:
25 Thread 0xb528f3e0 (LWP 2391) "Binder_1" __libc_do_syscall ()
at ../ports/sysdeps/unix/sysv/linux/arm/libc-do-syscall.S:44
#0 __l
I am getting similar symptoms (media-hub-server high cpu) , although I
didn't see unity8 restarting (perhaps it did and I didn't notice?).
I have attached a tarball of strace (clipped because it was just the
same after a point), gdb backtrace and a core file generated from inside
gdb for media-hub
This bug has been fixed for me in 3.1.5.1-1ubuntu1
