Overall rate: 1.79 (orange) - browser: 1.18, content: 0.62 There was a compiler change (VS2013 -> VS2015) recently which caused some signatures to be modified. This means some signatures that appear to have spiked actually haven't. I guess we're going to have the same problem when we start building beta and then release with VS2015. Aurora is probably going to switch back to VS2013, but nightly is going to stay with VS2015.

- Spike with signature shutdownhang | WaitForSingleObjectEx | WaitForSingleObject | PR_WaitCondVar | nsThread::ProcessNextEvent | NS_ProcessNextEvent | mozilla::layers::CompositorBridgeParent::ShutDown from 0 to 65 crashes in three days - filed - Spike with signature nsAutoCompleteController::HandleEnter (a few comments mention malware, one mentions "SafeFinder" in particular). The crashes on 48.0a2 all come from a single person, which does have a few suspicious DLLs. I've analyzed other reports, many have suspicious DLLs or addons. - Spike with signature tosqep64.dll@0x8f8c, fix now landed on inbound ( ) - Spike with signature shutdownhang | WaitForSingleObjectEx | WaitForSingleObject | PR_WaitCondVar | nsThread::ProcessNextEvent | NS_ProcessNextEvent | mozilla::net::nsHttpConnectionMgr::Shutdown, the related bug ( ) is marked as fixed in 48 as of 2016-05-04, but it looks like it isn't actually fixed - Spike with signature nss3.dll@0x1e66d0 | GetFileInfo, all crashes are from the same user


Overall rate: 1.24 (orange) - browser: 1.06, content: 0.18 - Spike with js::GCMarker::markAndTraceChildren<T>,, and js::GCMarker::lazilyMarkChildren,

New crashes in beta 5 (maybe this is interesting...)

    • Maybe JS issues


Overall rate: 1.04 (orange) startup crashes 0.14, shutdownhangs: 0.2 - Spike with OOM | large | NS_ABORT_OOM | mozilla::ipc::MessageChannel::OnMessageReceivedFromLink. The linked bug is, which is duplicated to, which is fixed in 47 and wontfix for 46. This appears to be a e10s-only crash? OK, but it's ~300 crashes in a week out of 229,397 crash reports. Do we care about this kind of spike? (Maybe. I commented in bug 1235633) - liz - Spike with RtlActivateActivationContextUnsafeFast | UserCallWinProcCheckWow, plugin related, similar to Here, we likely want to file a new bug, let's ask jimm - Spike with signature F1398665248_____________________________,, it doesn't seem actionable as it is a generic flash crash - Spike with nsTArray_Impl<T>::Clear | nsPluginFrame::SetEmptyWidgetConfiguration,, fix uplifted to aurora, no way to tell if it's fixed until it goes to beta - Spike with _dwrite_draw_glyphs_to_gdi_surface_gdi,, fix in nightly, requested uplift to aurora - Spike with mozilla::layers::BasicCompositor::DrawQuad, has a WIP patch - Spikes with GC-related OOM crashes, waiting on to get more informations about the crashes (allocation size) - Spike with Media-related shutdown hangs (shutdownhang | WaitForSingleObjectEx | WaitForSingleObject | PR_WaitCondVar | nsThread::ProcessNextEvent | NS_ProcessNextEvent | mozilla::MediaShutdownManager::Shutdown)
