48866 - M17 crash after sitting idle for 8 hours

Status: VERIFIED WONTFIX

(Core :: XPCOM, defect, P2)

Description

[Bob Kanefsky]

Build id 2000080712 on MacOS 9.

I left a browser window up overnight, and when I came back the Mac was in
Macsbug.  As nearly as I can tell from files written by another application
(SETI@home), the crash occurred after  about 8 hours.  As I recall, the page I
left displayed had no animations but might have been running a JavaScript
setInterval.  I'll attach a stack trace.  It referenced unmapped memory while in
an idle loop.

reassigning.

Comment 5

[Ray Whitmer]

This should be assigned to someone who has a Mac.  It is occurring in 
mac-specific code.

Scott, could you help verify this bug and decide who it belongs to?  Thanks.

Simon, could you look at this long enough to determine whether it needs to be 
solved in nsbeta3?  It all seems to be mac-specific code, and I am not set up to 
do that right now.

The stack tells me nothing. A full MacsBug stdlog would be better.

Comment 10

[Ray Whitmer]

Assigning to Simon for whatever further analysis and triaging are required.

adding perf keyword, setting to m19, setting to p2

No way I can even begin to investigate this without more information from the 
filer, e.g. what page wehre they sitting on, and is it reproducible.

Comment 13

[Bob Kanefsky]

It's not reproducible.  The page it was sitting on was a page I was developing 

which has since changed.

Comment 14

[Bob Kanefsky]

If it happens again, next time I'll know a stack trace isn't enough and you need 
a StdLog.  Marking as Verified since there's not enough to go on.

Perhaps more useful is the page that was being displayed for those 8 hours (and a 
list of windows open, if it was > 1).
