Recently (in the last few weeks), I've lost the ability to use Flash
in the browser on 9-CURRENT. Details:

FreeBSD m6500.local 9.0-CURRENT FreeBSD 9.0-CURRENT #0 r223911: Sun
Jul 10 14:53:05 CDT 2011
firefox-5.0,1
nspluginwrapper-1.4.4
linux-f10-flashplugin-10.3r181.34

When a Hulu or YouTube video "freezes", the audio still plays on for a
while (buffered I guess), but the Flash plugin eventually crashes,
leaving a gray box where the video once was.

I've also tried updating the NVIDIA driver to 275.09.07, to no avail.
I've tried with and without acceleration, I've built the driver with
and without Linux support -- same symptoms no matter.

I also tried a trick I read about in another thread, creating the file
/etc/adobe/mms.cfg and setting various options off/on...

Below is the console output I see when I run Firefox and I experience
the issue (though I suspect the output itself is more a symptom than a
diagnostic):

Any tips on debugging this?

I started bisecting kernel, world, nspluginwrapper, and flash plugin
versions starting from stuff I had laying around from early June 'til
today, and I saw the same behavior no matter what versions of software
I was using.

Then, it hit me -- I upgraded my RAM from 4GB to 16GB about a few
weeks ago, and that's around the time I remember last using flash in
the browser. So, I opened up my computer, removed 8GB of memory (and
added back the old 2x2GB sticks so the computer would boot -- I have
another 8GB loaded in slots under the keyboard), giving me a total of
12GB of memory.

I updated kernel, world and ports, and gave Hulu a whirl. No issues
whatsoever. Youtube was also OK. I've been able to use flash for quite
a while now, with no issues.

So, there is something going wrong with the combination of software,
hardware (NVIDIA with any version of their drivers), and the large
memory size, in my case 16GB. Drop it down to say, 12GB, and
everything is stable...
