Google Chrome causing system to freeze

Question

Google Chrome has been sporadically causing my system to freeze. It may work fine for a few days, or for less than twenty-four hours. Without warning, the browser will suddenly begin reading and waiting on its cache, and become unresponsive. When I try to force quit the application, the system locks up and Finder will freeze but imputs are still responsive, causing me to have to do a hard reboot. Once rebooted, Spotlight re-indexes my hard drive [which I believe is a separate issue (mdworker unable to talk to lsboxd)]. This only occurs with Google Chrome and is not replicable with other browsers or applications.
I have cleared all caches and reset my PRAM and SMC controller, but the issue persists. Any thoughts?

Answer 1

There are several "shared libraries" in the Extensions folder. There is also "Shared Library Manager" (and "Shared Library Manager PPC") which are not shared libraries themselves, but provides support for using shared libraries. Since you know the extensions, can you post back with their exact file names?
