CrashStats 2012-09-25.png

Nightly :


  • Need to wait for ADU/Crashes to be more stable. Looks good so far.

Release :


  • Down at the bottom of the report we are seeing over 200 crashes in the nightly that have sigkills with address locations for nightly
    • ex: 1 2 ; see : starting from 87 down in the nightly report
    • Need to figure out how to make this actionable; maybe get a stack trace through minidump?
  • bug 752828 looking at the patch from bug 741224, it might be helpful to get the API levels for the crashers?
    • Need STR from QA.


  • bug 745512 #6 on release, not shown in beta and above.
  • bug 750217 to be monitored for next beta release.

See Mobile Notes for Mobile specific Socorro notes

  • Had a meeting on the crash reporting story in terms of UI and privacy on Friday, work now happening on what the UI should look like, implementation work needed.
