Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[pdm]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

From time to time Firefox will stop responding and chew up 100% CPU.  I did a
ktrace on it and noticed it was spewing the same thing repeatedly, non stop.
It does not seem to be associated with any particular web page, I haven't found
a common case that makes it happen.

   241 firefox-bin CALL  ppc_gettimeofday(0xf00b3d00,0)
   241 firefox-bin RET   ppc_gettimeofday 1123075689/0x42f0c669
   241 firefox-bin CALL  ppc_gettimeofday(0xf00b3d00,0)
   241 firefox-bin RET   ppc_gettimeofday 1123075690/0x42f0c66a
   241 firefox-bin CALL  ppc_gettimeofday(0xf00b3d00,0)
   241 firefox-bin RET   ppc_gettimeofday 1123075691/0x42f0c66b

This bug is probably the same that causes it to hog the CPU after a lengthy standby.

The bug can be easily repeated by leaving a laptop in standby (and Firefox on a
fairly complex web page) a couple of hours and then resume. It always happens if
I have a large news page such as http://aftonbladet.se open overnight in standby.

It could be a problem with some scripting language on such pages, causing
Firefox to "eat up" the lost time when it was in standby.

A patch should compare the last time with the current time and if the diff is
too large, simply skip ahead to the new time.

You could probably also trigger the bug by advancing the system clock a couple
of hours.

Bug 371398 might be related as it also shows gettimeofday in the stack trace.

I reported aftonbladet and expressen as broken Websites

'The first 30seconds when entering the site, refreshing, visiting urls on the site cpu usage is 99%. This doesn't happen in Windows but has happened for everyone I asked in linux.

This behavior has been consistent atleast the last 4years'

Probably a dupe of bug 273310?
