I'm using mozilla 1.7.12 on FC4.
My app plays a number of flash files for 30 seconds one after the other.
After a few hours things will go wrong.
I've seen two problem:
1) mozilla memory use grows until it runs out of VM and aborts.
2) Flash plugin call free() which calls abort() and mozilla hangs
Is this a know problem? Are there any fixes/workarounds?
I attached gdb and did thread apply all bt. Lots of the threads
are blocked like this:

I'm going to turn on MALLOC_CHECK_=2 to see if that will help track down
the problem. An acceptable workaround would be to get the process to
exit as I have a driver program that will relaunch my app.
