iTunes uses over 1.5GB of memory

Question

I use an old (2007) Mac Mini (10.7.5) to serve iTunes (11.0.2) and recently it has started using a lot of memory. It has never been what you would call efficient in terms of memory allocation, but 1.5+GB seems high even for iTunes. It starts out around 115MB and every so slowly climbs even with nothing using or accessing it.

Anybody else seen this?

And no, purge does not help. :)

The machine has 4GB installed but of course OSX sees 3GB. The iTunes library is about 300GB. There are no other active processing going on and the machine is not used as a desktop. It is not actively importing new content or even playing content at all. Mostly it just sleeps. When launched, iTunes uses a bit over 100MB according to Activity Monitor.

All it does is run iTunes so various iOS devices can wirelessly sync when they want to. I restarted iTunes yesterday and it used 113MB. This evening I came back and it is using a little over 1,000MB and growing ever so slightly.

Answer 1

I believe I have figured it out. I relocated my iPhoto library but had never opened it afterwards in iPhoto. I believe that iTunes has a memory leak in handling when it tries to access the library that no longer exists. Once I opened iPhoto and selected the new library location the memory leak in iTunes stopped.
