Stability Report


  • Small Socorro release coming tomorrow, no major changes for developers.
  • Work being started to support ESR in Socorro within this quarter.
  • bsmedberg and ted are working on some stackwalking issues that cause wrong signatures or stack frames to appear:
    • bug 726570 – MSVC2010 issues
    • bug 709209 – browser-side hang signatures (even on MSVC2005)
    • The patches in the former might fix the latter, but we don’t know for sure. Seems like they will improve stackwalking significantly in any case and might change signatures due to that.


Firefox 10 Top Issues

  • No new signatures have cropped in 10.0.2 so far
  • bug 725945 Crash in nsCacheService::Unlock
  • bug 718389 PR_EnumerateAddrInfo – only 5 crashes so far in 10.0.2, over 4000 in the past week on 10.0.1.

  •<address> are the top crashes for Beta; low ADU causes high spiking with low number of crashes (9) crashes show 400/300 crashes per 100 ADU.
    • Note: This crash is fixed in Maple but does not apply to current M-C. For more details see: bug 721489 – Older Adreno 200 drivers intermittently crash when uploading RGB565 textures with glTexImage2D
