    Is this a known bug in OS X's activity monitor ? Seems to be some kind of number under- or overflow:

    The displayed shared memory size of my Safari process fluctuates between small numbers in the MB region and the obviously incorrect 2^24 TB (or 2^64 bytes = maximum addressable memory space of a byte-addressable 64-bit computer?).

    Any insight on/experience with this behavior ? Is this known? Not that I'm so worried about it, but I'm curious... :)

    This is a common bug with activity monitor. Happens to me all the time with java. No worries.
