Memory totals not adding up

[Darhl Thomason]

I'm using Monit 5.2.5 running on Debian Squeeze

When I look at my Monit web portal I see items similar to this:

Apache

running

9d 3h 27m

0.0%

0.6% [10692 kB]

But when I do 'ps aux | grep apache' I get:
address@hidden:/# ps aux | grep apache

it adds up to 8.1% memory.  Why is it only reporting 0.6% Memory?

There are other/similar items examples Amavis, Spamassassin, etc.

Thanks!
