Comment 39 for bug 177856

I think this bug is related to bug 212877. Just like this bug, the people there report having 64-bit SMP (multicore/multiprocessor) systems and it was brought by Mozilla Firefox 3.0 Beta 5. The difference, however, is that bug 212877 relates to Mozilla Firefox crashing, not just Flash alone.

On April 6th, I decided to test if the Firefox 3 Beta 5 update was causing the problem. I had not upgraded to Firefox Beta 5 (didn't check for updates), but found the update to Beta 5. I updated all other (irrelevant) packages, except firefox, firefox-3.0, firefox-3.0-gnome-support, and firefox-gnome-support. I then opened Firefox from the console (to see any error messages) and proceeded to test extensively and try to make nspluginwrapper and/or flashplugin crash. This including opening many Youtube videos as tabs, and refreshing random Youtube tabs. Firefox did slow down dramatically, and it did "freeze" for a few moments, but Firefox/flashplugin/nspluginwrapper did not crash. The Youtube videos continued to play. No error messages relevant to nspluginwrapper/flashplugin were on the console.

I then upgraded the specified packages. Once again, I opened Firefox from the console (to see any error messages) and proceeded to test extensively and try to make nspluginwrapper and/or flashplugin crash. Nearly immediately, without opening more than one or two Youtube video tabs, the flashplugin crashed and nspluginwrapper outputed errors on the console.

I think, unless someone knows the solution, we should narrow done what difference in Firefox 3.0 from Beta 4 to Beta 5 caused the problem. I think I should look at Swiftweasel as well.
