Is this still happening? I took a look at your pfile, and everything is fine (the correct amount of items there). It looks like a memory leak, probably cleared up with a reboot and/or logging out & back in.

So long, and thanks for all the fish!

Aye, was cleared up with a reboot.
Logged in/out several times which did nothing, but after it has been rebooted I have noticed the correct number of items.
Thanks!
