I'm trying to determine why my app, which is normally such a quiet program, has, out-of-the-blue, started chewing up 100% of the CPU time (according to top on a DP machine). What's bizarre is that I ran sample, and 98% of the logged stack tops are calls indicating the app is asleep (mach_msg_trap and select). So where is the excessive CPU usage coming from?

I noticed then, at the top of the top display, the line of CPU usage indicating 20% user, 40% system, 40% idle. Maybe the system usage is being caused by me (thus showing in my top %CPU column) but isn't showing up in the sample output.

How do I track down excessive CPU usage classified as "sys" when sample shows nothing? How do I figure out what app it is, and how do I track it within that app?

Thanks for any suggestions.
