Stability Report

Desktop

• Trunk stability is pretty good
  • https://crash-analysis.mozilla.com/chofmann/20110725/top-8.0a1.html
  • 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).
