Status: RESOLVED DUPLICATE of bug 998145

(Firefox OS Graveyard :: Performance, defect, P1)

Attachment: logcat_20140429_1207_facebook_scrolling_crash_.txt

Description:
When scrolling through the Facebook feed, the app will often close when it attempts to load more tweets.  This does not necessarily occur on every load, but will eventually occur if enough posts are loaded.
Clicking a specific post seems to delay this close.
Prerequisites: Have an active Facebook account.

Repro Steps:
1) Update a Tarako to BuildID: 20140429014002
2) Open and sign into Facebook
3) Scroll through until additional posts load taking care to avoid opening any specific post
4) Repeat step 3 until the app closes

Actual:
Facebook will close after loading more posts.

Expected:
Facebook does not close when scrolling through posts.

Per discussion on other bugs - FB apparently is a must have for Tarako, so I'm bouncing this over to the perf component for perf evaluation.

chances are we need profiling.

Comment 7

[Joe Cheng [:jcheng] (please needinfo)]

triage: 1.3T+ as facebook is required for Tarako

I think this might be a dup of bug 998145 ?

Hi,

I check the log and found it might be low memory caused.

Who can analyze attached logs and figure out what's going on this issue?
