I did some tests, some interesting results
my processes no longer seem to be 300mb. which is good. however,
when that happened, i was seeing a 300mb process and then 6mb in a
child. now i'm back to seemingly unshared memory.
based on my tests below, i *think* that it may have been because i
was doing apachectl restarts, and not clean stop/starts
i've noticed that my parent and works take on an additional 30mb of
memory every time an apachectl restart is issued.
i thought to myself, ugh - "thats what you get for not using a graceful"
well , graceful does the same thing.
i'm more lost now than i was yesterday
