[Blocking Requested - why for this release]:
It might relate to memory management.

Per offline discussion with William, I don't think it's a Gaia issue. The device ran out of memory, and it was busy on releasing memory. However, since it's caused by monkey, we can't do anything without the dead device. I've asked William to keep the device intact if it happens next time.

Thanks Evelyn.
Sorry. I restarted the device and cannot reproduce it now.
I would like to monitor this bug.
If Monkey test cannot catch it next week, I would like to close this bug.
Thanks.

--- Needinfo "whsu" to update this bug. ---

Ni Danny to monitor this issue in monkey tests.
No crash with non-optimized build can be found after the weekend test in 8/2-8/3.
We are testing optimized again.

Remove NI:wshu since Monkey test has transferred to Danny and Danny is helping on it.

Okay! I will discuss the bug with Denny since he is in charge of Dolphin monkey test.
Thanks!

Didn't meet this issue on 8/5 monkey test with 3 devices and optimize build, below are the results:
1. No b2g was killed
2. No any hang issue
3. There are two crashes on two devices, see https://bugzilla.mozilla.org/show_bug.cgi?id=1038047
