Benson, could you please provide some more information?

Sure, I can provide more information...

1) What build are you using?
I'm running Mozilla build 2002041507 on RedHat 7.2.

2) Do you have the Flash plugin installed?
Yes, I had installed the flash plugin from the macromedia site.  I downloaded
the gziped file and moved the libflashplayer.so and ShockwaveFlash.class to my
/usr/local/mozilla/plugins directory.

[bchen@hulk plugins]$ pwd
/usr/local/mozilla/plugins
[bchen@hulk plugins]$ ls -la
total 964
drwxr-xr-x    2 root     root         4096 Apr 16 10:04 ./
drwxr-xr-x    9 root     root         4096 Apr 15 11:56 ../
-rw-r--r--    1 root     root       948056 Apr 16 10:15 libflashplayer.so
-rwxr-xr-x    1 root     root        19396 Apr 15 08:32 libnullplugin.so*
-rw-r--r--    1 root     root         2363 Apr 16 10:15 ShockwaveFlash.class

3) Were you playing mp3s or anything like that when you went to this site?
I usually have StarOffice, Visual SlickEdit, and DvVisualizer running but I
don't play mp3s.

I have been able to reproduce the frozen Mozilla consistently by going to
http://www.z-buy.com.  In fact, I've tried some other flash enabled sites and it
would freeze as well.

Reporter:
could it be bug 58339 ?

Comment 4

[Boris Zbarsky [:bzbarsky]]

This is almost certainly bug 58339.... Could you please run:

lsof | grep "dsp"

(lsof may live in /usr/sbin and not be in your PATH)

and see whether anything has /dev/dsp open? The program name would be in the
first column of the lsof output...

Yeah, it looks like I had an artsd daemon running... not quite sure what uses
that.  Anyway, I went ahead and killed it and now Mozilla can load up that page
just fine.  Thanks!

[bchen@hulk plugins]$ lsof | grep "dsp"
artsd      1244 bchen    6w   CHR       14,3              229663 /dev/dsp

Great.  :)  Good to know it works for you.

artsd is a sound daemon that lets multiple programs talk to the sound device at
once without blocking (it multiplexes the streams).  Unfortunately, that means
it itself has to hold the sound device open....  You could make Mozilla use
artsd (not sure how that's done, but there are howtos on this) and that would
also eliminate the hang.

Thanks for your quick responses, btw!
