Add-ons

Stability

Aurora

crash rate: 2.7 (red) - browser 1.3, content 1.39 big spike in the last few days

Spikes:

  • signatures: _chkstk, UnmarkGrayTracer::onChild, js::ObjectGroup::traceChildren, JS::CallbackTracer::onShapeEdge
    • _chkstk: crashes rose from 0 (2016-03-26) to 248 (2016-03-28)
    • for the others: crashes were at 0 (2016-03-25) and rose to respectively 248, 99, 54 (2016-03-28)
    • the crash reason is always EXCEPTION_STACK_OVERFLOW
    • in all the cases, the backtrace is useless (reduced to one element)
    • https://bugzilla.mozilla.org/show_bug.cgi?id=1259699 has been fixed (in Nightly) and we should have better information (signature or backtrace) to fix these issues
      • If the fix is helping, will request uplift to Aurora

Topcrash

Beta

crash rate: 1.33 (red) - browser 1.17 , content 0.16

  • Bug 1255737 - Async shutdown crash with "MediaStreamGraph shutdown: blocking on msg thread"

crash rate: 1.16 (red)

trusteer rapport crashes still in high numbers (responsible for ~6% of all crashes on 45.0.1) - bug 1255026

    • not uplifted to Beta46
