95539 - Lock up with flash plugin

Status: VERIFIED WORKSFORME

(Core Graveyard :: Plug-ins, defect)

Description

[Sean Harding]

Mozilla 0.9.3 on Linux 2.4.7 locks up on pages that use Flash. It doesn't happen
instantly. Often it seems to happen when I try to leave the page. An strace on
mozilla while it was in this state showed an infinite loop of:

gettimeofday({997929331, 137820}, NULL) = 0
ioctl(50, SNDCTL_DSP_GETOSPACE, 0xbfffe698) = 0
select(0, NULL, NULL, NULL, {0, 11000}) = 0 (Timeout)
gettimeofday({997929331, 158018}, NULL) = 0
ioctl(50, SNDCTL_DSP_GETOSPACE, 0xbfffe698) = 0
select(0, NULL, NULL, NULL, {0, 11000}) = 0 (Timeout)
gettimeofday({997929331, 177829}, NULL) = 0
ioctl(50, SNDCTL_DSP_GETOSPACE, 0xbfffe698) = 0
select(0, NULL, NULL, NULL, {0, 11000}) = 0 (Timeout)

The http://www.nobodyhere.com/justme/ is an example this has recently happened
with, but it's not specific to that page. It's happened with at least ten Flash
pages in the last week or two.

Are you by chance listening to music/audio when this happens?  XMMS?  LinAmp? 
FreeAmp?  CD?  (See bug 58339)

Comment 2

[Sean Harding]

Not this time at least. I have used xmms in the past since last reboot, but I
didn't have it running at the time of the lockup. I didn't have any applications
running that use sound (all I had was mozilla, several rxvts, ssh and
WindowMaker [with no sound support]).

Reporter, can you try a recent nightly build available at:

This still happens in 2001100514 on linux 2.4.9.

Comment 5

[R.K.Aa.]

when it happens, can you please do  a lsof /dev/dsp
(lsof often found in /usr/sbin)
Then tell here there's any output from it.

Comment 9

[Sean Harding]

This still happens for me each and every time I load a page with Flash. It
doesn't always happen immediately -- sometimes it's minutes or even hours later.
But it's correlated to loading a Flash page 100% of the time. No Flash == no
lockups. Flash == lockups. Every time. Tonight it was with build 2001120906.
lsof on /dev/dsp showed nothing (no audio related devices were open by any process).
