    How much RAM do you have installed? 8 GB? The pageouts are huge (which would account for the accumulating disk usage > the swap space) , and I don't think it is due to insufficient RAM. This appears to me as just a huge memory leak. The machine isn't freeing up inactive RAM for reuse. Try reinstalling ML from the recovery partition.

    nbar - agreed. This is a huge memory leak in iTunes or something that iTunes runs. Something triggers iTunes to gobble up memory and the system responds by allocating more and more swap space until my disk is full. I've reinstalled iTunes and I'll see if it happens again.

     

    When you say "reinstall ML", to what are you referring?

    Confirmed - it is iTunes. I'm running iTunes 11.0.5 on Mac OS X 10.8.4. I've reinstalled iTunes from the binaries on apple.com. And whenever I leave iTunes running overnight, at some point it starts sucking up memory and forces swap space to consume all available disk within 15-20 minutes. Note: it runs fine for hours, but at some point encounters an internal error (I'm usually asleep at the time) and eats up all available swap space.

     

    Any clues, guys at Apple? Anybody else seeing this problem?

     

    Or, anybody else having a "disk runs out of space but clears up after a reboot" problem that might actually be the same as my iTunes running beserk problem?

     

    Here's the first few lines from my top output (I have a diagnostic script that starts collecting information as soon as disk availability drops below 97%):
