Status: VERIFIED DUPLICATE of bug 868741

(Firefox OS Graveyard :: Gaia::System, defect)

Description

[J Zimbrick]

Attachment: Crash screen that is displayed after the crash from the music app.

Description:
  When the user launches 10+ apps and opens the task manager to close all but one, when opening the last app the device will crash.

Repro Steps:

1. Update Leo device to build 20130506070204.
2. Launch the music app and begin playing a song.
3. Return to the homescreen and open several apps. (At least 10 or so.)
4. Hold the home button to open the task manager screen.
5. Close all of the apps except for the music app.
6. With the music app as the last one in the task manager, tap on it to open the music app.
7. Observe that the phone appears to freeze. Music may or may not continue to play and all buttons are unresponsive.  If the user waits long enough a crash screen is displayed. (See attached picture.)

Actual:
 Device crashes when launching the last app.

Expected:
 Device does not crash and the last app is launched properly.

Environmental  Variables:
Kernel Date: Apr 25

Notes:
Repro frequency: Somewhere around the 80% range, seen on 3 different Leo devices.
Q Analysts Test Team Priority: Pri 1
See attached screenshot for more info.

Notes:

The steps provided are just the most consistent way I've found to repro this issue.  Other testers have had it occur without music playing and with a different app as the last one opened.  Potentially a memory issue?
