Stability Report


  • Trunk stability is pretty good
    • Still some old crashes appearing in older builds
    • Bug 671916 - new linux crash regression. #5 in overall crashes on the trunk in the past week.
    • Bug 673977 - increase in this signature on the trunk that we think is related to the GC instrumentation patch we checked in.
    • New signature appeared yesterday nsRefPtr<nsXPCClassInfo>::~nsRefPtr<nsXPCClassInfo>() | nsCycleCollectingAutoRefCnt::decr(nsISupports*) - still needs to be logged.
  • 10.7 related crashes
    • Bug 670842 - is our top Lion specific crash and has been rising steadily since 10.7 was released.
  • Increased feedback reports - "app is crashier for 6.0 than 5.0"
    • We looked into this and found a measurable increase in Flash related hangs - Bug 618683
    • No clear site correlations but many of the comments mention youtube.
    • Some analysis pinpoint the regression to a period back in May but we are still trying to solidify this.
    • When we moved to beta, this hang really spiked ie: 1400 a day with 1 million users (5.0 has about 400 a day with 60 million users).


  • top crash we were tracking Bug 671960 was just fixed.
  • Bug 672287 - Get symbols for libc for most common Android installs
    • Bug 672564 - Get symbols for libc for our tegras in test automation


  • App demo next week
