740101 - Investigate hang spike in Firefox 11 (Flash Version 11.1.x)

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

[Marcia Knous [:marcia]]

For the past few days the explosive report has been showing a marked increased in Flash hangs in Firefox 11: See https://crash-analysis.mozilla.com/rkaiser/2012-03-27/2012-03-27.firefox.11.explosiveness.html.

Looking at  few of the signatures I see the following correlation to either the .62 or .63 version of Flash 11.1

hang | NtAllocateVirtualMemory
11.1.102.62 49.457 %  455
1.1.102.63   36.087 % 332

hang | ZwAllocateVirtualMemory
11.1.102.62 36.181 % 72 
11.1.102.63 33.668 % 67

hang | F1854743955______________________
11.1.102.62 44.125 % 522 
11.1.102.63 38.462 % 455

hang | F1511491252_________________________________
11.1.102.62 42.529 % 185 
11.1.102.63 39.08 % 170

I also filed Bug 739445 the other day for one signature but there also quite a few more:

hang | F1537816679________
hang | F_174604184_______________________ 
hang | F_397880079__________________________
hang | fastcopy_I | _VEC_memcpy | 
hang | F_966691389_____________________________ 
hang | F_797141883___________________________________________________________

Today's report still shows some signatures spiking on Firefox 11: https://crash-analysis.mozilla.com/rkaiser/2012-03-28/2012-03-28.firefox.11.explosiveness.html

Sheila/Marcia - how should we move forward here? Do we think that we'll have any success with reproducing if we pull URLs and try to find a matching affected config?

I don't think there's anything still interesting about a spike in Flash 11.2, esp. as 11.3 made stuff worse enough that this spike is probably not even visible any more.
