If I use SeaMonkey (2.49.2 which seems to be the latest version) for a
while and visit different sites and open and close windows and such,
eventually it gets to the point where it slows down to the point of almost
hanging and I need to close a bunch of windows (which takes ages since
SeaMonkey is running so slow) before SeaMonkey will start being usable
again. In some cases I have to force-close SeaMonkey completly because its
totally hung and simply wont respond to my inputs.
I have noticed that using Google Maps and panning around is a great way to
make this hanging/freezing/etc happen faster.
The last time it totally hung Task Manager told me there was almost no free
physical memory (I have a total of 8GB) and that SeaMonkey was using a very
large amount of RAM. I also noticed that when I attached to SM with a
debugger, it was hanging somewhere in the windows memory allocation code
(i.e. that was what was on top of the call stack) with some mozglue memory
allocation code the next thing after the windows code.
Is this kind of hanging/freezing/slowdown a known thing? Is there a
bugzilla bug (or bugs) that cover this issue? Is there anything that can be
done to mitigate or work around the issue? Could one of my plugins (I use
Addblock, ChatZilla, DOM Inspector, Geolocater, JavaScript Debugger and
User Agent Switcher as extentions plus Acrobat, NVIDIA 3D, Silverlight,
Window Live Photos and Flash as plugins) be the cause of the problems?
