Stability

Aurora

awsy rate: 5.62 (browser 1.09, content 4.53) telemetry m+c-s from sunday: 2.92 crashes/kuh (-0.54 to the week before, -0.98 to two weeks before, -0.26 compared to last cycle)

[marcia]

• https://bugzilla.mozilla.org/show_bug.cgi?id=1320048 continues to the top browser crash (Touchbar on MacBookPros crashing on sleep)

Beta

awsy rate: 0.91 (browser 0.68, content 0.23) telemetry m+c-s from sunday: 3.09 crashes/kuh (+0.18 to the week before, +/-0 to two weeks before, -0.07 compared to last cycle)

[philipp] 51 rc1

• worst crash, https://bugzilla.mozilla.org/show_bug.cgi?id=1322554 (internet download manager issue)
• major crash fixes going into rc1 all look successful and volume went down to 0 for those signatures:
  • js::IsDerivedProxyObject https://bugzilla.mozilla.org/show_bug.cgi?id=1308800
  • memcpy | NS_CopySegmentToBuffer https://bugzilla.mozilla.org/show_bug.cgi?id=1330273
  • CDIProperties<T>::SetValue https://bugzilla.mozilla.org/show_bug.cgi?id=1328872

• a handful of additional crash fixes are going into rc2:
  • OOM | unknown | js::AutoEnterOOMUnsafeRegion::crash | JSRuntime::createJitRuntime https://bugzilla.mozilla.org/show_bug.cgi?id=1331606
  • mozilla::dom::TabChild::RecvAsyncMessage https://bugzilla.mozilla.org/show_bug.cgi?id=1331193
  • mozilla::gfx::DrawTargetD2D1::Fill https://bugzilla.mozilla.org/show_bug.cgi?id=1331274
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1328642

• rc1 is affected by the crash pattern from https://bugzilla.mozilla.org/show_bug.cgi?id=1316022 for particular amd cpu models (7,5% of browser crashes)
  • will likely go away in the next build (or morph into something else)
  • discussion on uptime ml that we shouldn't care about those cpu models anymore (3.7% of users have them, we shipped 50.0 with the same crash pattern and it caused around 1500 additional daily reports there)

[marcia]

• Mobile: https://bugzilla.mozilla.org/show_bug.cgi?id=1331808 seems bad, but the bug mentions it happens in "limited scenarios"
  • can cause GBs of data usage while app is inactive - very bad/expensive user experience :-/
  • We might consider doing another Fennec RC for this.

Release

awsy rate: 0.93 (browser 0.69, content 0.23) telemetry m+c-s from sunday: 2.77 crashes/kuh (+0.09 to the week before, +0.05 to two weeks before)

[marcia]

• Spike in http://bit.ly/2jBUPrW - Comments mentions issues with crashing when installing Java. Affects beta as well. Will file a bug after the mtg.

Nightly

[marcia]

• Crash rate is about the same as reported at Tuesday's meeting
• Filed Core | Dom https://bugzilla.mozilla.org/show_bug.cgi?id=1332095 - there is already a patch in the bug
• Latest Uptime crashes reported: https://wiki.mozilla.org/Platform/Uptime/NightlyCrashTriage/2017Q1#2017-01-18_-_jchen

Mobile

[marcia]

• https://bugzilla.mozilla.org/show_bug.cgi?id=760394 seems pretty high on release (and affects beta as well). It is #3 and #5 which combined total over 20K crashes which is almost as large as the dalvik crash. I added that information to the longstanding bug.
