After letting our aluminum iMac running Leopard 10.5.7 sleep  
overnight, I woke it and noticed the hard drive was running for more  
than a few seconds.  Unusual, while just getting into Safari and  
Mail.  Thinking that Spotlight was indexing unexpectedly, I launched  
Activity Monitor and found only one "md" item at "0.1" under CPU  
blinking on and off.  I took three screen shots, the first two while  
the drive was still spinning, and the third just after it stopped, all  
at 10:37 and 10:38 AM.

I did not catch the "md" item.  With the screen showing Active  
Processes, the first two screen shots show Process ID 465, Name find,  
User nobody at the top.  The CPU counts were 9.8 and 41.4.  Window  
Server was 3.6 and 2.5, with everything else at 1.5 or below.  The  
little graphics at the bottom show columns rising to about 40 to 70%.

So what was "nobody" doing?  Should I care?

Bracketing the times listed above is this from the Console All

Are there any other logs I should look for?  In Console, system log is  
greyed out. ??
