Hi Managers,

This is strange, I couldn't figure out. I did

#/usr/ucb/ps -auxww
 USER PID %CPU %MEM SZ RSS TT S START TIME COMMAND
...
 When I added up %MEM column, it's 156.66! Is this
suppose to be less than 100 since it's showing the
percentage? I tried /usr/sbin/ps, it's the same, these
two ps are probably the hard links cause they have the
same inode number.

This is a heavily loaded 2.6 box. Anybody has a good
explanation for this? Thanks and I'll summerize.
