The server is running fine like this.
,,,

When I noticed the server starting to get sluggish and the load average
was around 8.00-  9.00,,when I run 'top' with no parameters I would see
httpd entries about 6-8 times and yes it showed around 25% mem usage
each. I have never even seen httpd listed when running top before(with
no extra parameters). This has only happened about 3 times,and it seems
like it happened after a power outage at my house.Probably just a
coincedence?

Since I posted this and shut off httpd for 10 mins then restarted I have
never again seen httpd even listed in top ( this seems to be 'normal")
with no parameters.
Just wonder what makes httpd load the server in this fashion and what
spawns it?

Thanks,
Barry
