Unknown processes, please advise!

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.
