Status: RESOLVED DUPLICATE of bug 1256049

(Core :: Storage: IndexedDB, defect, P2)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

This bug was filed from the Socorro interface and is 
report bp-beeace1c-cc45-4b62-9616-2a3162150816.
=============================================================

I've observed this crash twice while playing Netflix using EME/HTML5 on Windows in Nightly 43.

I think it's a race. I've only seen it on a low end Core i3 laptop with my Firefox profile on a slow SD card. In the report above, I also had NSPR_LOG_MODULES set to verbose media logs, and the NSPR_LOG_FILE located on the SD card too.

I experienced the above crash when refreshing a page playing "Black Hawk Down", and I observed in the browser console just before the crash:

An IndexedDB transaction that was not yet complete has been aborted due to page navigation. wwwplayer-3.0000.043.051.js:559:0
AbortError wwwplayer-3.0000.043.051.js:559:0
NS_ERROR_UNEXPECTED:  <unknown>

Reach out to me (cpearce) when someone wants to debug this, and I'll provide information on how to make Netflix working...

Jan, Andrew: It would be good if we can get someone to look into this. I think it's low volume, but I can't tell because Netflix is currently not serving EME to Firefox Beta/Release channel users; so we won't be running this code in Beta/Release, so we won't be getting crash reports for it.

I can only repro this on Windows in Nightly, because Netflix are currently only serving EME to Windows/Nightly users.

Chris and I spoke about this via email.

Lowering priority of bugs that don't need to block initial EME rollout.

I just observed this crash in release on an Intel i5, the crash for me occurred on start up. I started up firefox, it was being a little slow, i went to navigate to a site and while trying to do so firefox release version crashed on me.

Jan and Kyle: this isn't a top crasher but I see a bunch of recent reports from Windows users. Can one of you investigate?

I bet AutoClose is screwing stuff up somehow at http://hg.mozilla.org/releases/mozilla-release/annotate/146f494b6a79/dom/indexedDB/ActorsParent.cpp#l17408

Nope, it's coming from CloseConnectionRunnable. https://crash-stats.mozilla.com/report/index/35445dad-fa52-461b-bcde-689402160211
