Hi,
Please check again, because we tested nba on our device and it's works fine.

Gur,

Issue does indeed repro on the following:

We use builds published by Telefonica- flashed the latest build into our Unagi device and checked out the specified Gaia commit, and it still doesn't crash for us!

Maybe some more info- what network are you using? WiFi, 3G, 2G?
any developer flags on?
device language?

I was using Wifi.
> any developer flags on?
Only Remote Debugging.
> device language?
English.

Could this possibly be an out of memory issue as commented on bug 849320, comment #1?

[Evyatar 'Tron' Amitay (everything.me)]

could be, but I assume all Unagi hardware is the same, so I don't see a reason for it to happen to you but not to us.

how can we check if it's OOM?

I will refer you to Naoki Hirata, the one who wrote comment #1 in bug 849320 since I do not know how to check if it is an OOM issue.

Naoki- can you shed some light on this for us?

If it was a crash you would see something like sigkill in the log, a crash report dialog, and/or a crash signature id in /data/b2g/mozilla/Crash Reports/submitted.

actually this might be a real crash : 03-07 15:39:38.726: I/Gecko(108): [Parent 108] WARNING: waitpid failed pid:2579 errno:10: file ../../../gecko/ipc/chromium/src/base/process_util_posix.cc, line 260

mlevin do you have a crash file in /data/b2g/mozilla/Crash Reports/submitted?  Please attach that in the bug.  It's important that you place this information if you truly crashed.

nhirata: no crash report but now that I know where to look I will keep an eye out for that in the future.

[Evyatar 'Tron' Amitay (everything.me)]

great, so if it happens again and you get a crash report- we'll be be able to check it out properly.

still weird that it doesn't happen here, but it might be a difference between the gecko builds I guess.
