637515 - flash crashes unexpectedly higher on 10.2 than 10.1 for flash apps on face book.

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

[chris hofmann]

To find which flash apps on facebook are currently the "crashiest" and which versions of firefox and flash are associated with the crashes and hangs I've run a number of queries.

First I looked a variety of flash apps running on facebook with this query on the crash.csv files to filter on  crash/hang reports that mention "facebook" and "apps"  then use this to also report the version number of firefox and flash around at the time of the crash.  then I also looked exclusively at problems related to firefox 3.6.13
 
grep facebook 20110227* | grep apps | awk -F\t '{print $2,"/",$8,$22}' | awk -F'/' '{print $4,$NF}' | sort | uniq -c | sort -nr | grep 3.6.13 

the output from that command shows a shift to the highest percent of problems now visiable on frontierville, whereas previously its been farmville, inthemafia, mafiawars, and others.  in nearly every case it shows a higher incidence of flash problems on flash 10.2 v. 10.1.  here is the full ranking.

for 4.0b12 it looks like the crash problems have shifted to hangs, so we aren't getting flash version info

grep facebook 20110227* | grep apps | awk -F\t '{print $2,"/",$8,$22}' | awk -F'/' '{print $4,$NF}' | sort | uniq -c | sort -nr | grep 4.0b12 | more

drilling down further on reports that mention frontierville it looks like the hang signatures are spread over a number of ntdll.dll@ addresses in the browser side hang reports

[smadayag]

would you have a link to a crash-stat incident that i can map to a signature?

Comment 4

[chris hofmann]

just plug in any of the signatures above to the search box on crash-stats.

Here a couple of lists with links to idividual reports.
