    Hi,

    Recently I found 2 processes in Snow Leopard which I can't seem to identify. I'm unable to find anything on Google to suggest what they may be. The two processes are:

    cvmsComp_x86_64
    cvmsComp_i386

    Any ideas? Suggestions? They don't exactly use up much processor or memory, but I've never noticed them until recently.

    Do an Inspect on the process (and get a Sample) from Activity Monitor and see what application is stems from if any.

    I think they're a part of Snow Leopard's OpenGL framework.

    Thank you both for your prompt responses :). They both stem from "launchd", by the way.

    That's correct.
