iTunes consumes all RAM (Random Access Memory) since the Update to 11.0.5

Hi there everybody!

As Already stated, since I updated my iTunes 11 to version 11.0.5 it started freezing my entire Computer.

Having a look to the Actitiy Monitor, which I have running all the time, I saw that iTunes was consumming all availble RAM (9,5GB). Normal should be around 200MB.

This resulted in freezing of all applications until the 'force quit' menu popped up with a warning and right after that my Mac was completely blocked, I could just move the mouse.

After restarting the Computer, I tried it again and after some time iTunes result again in overloading...

I tried to turn of iTunes Match for now as the update fixed an issue with iTunes in the Cloud, I also turned of simultanious downloads and unsubscribed from all my podcasts. Does anybody else have another idea?

thank you and

Kind Regards,

MiCo
