A slot is a placeholder for a child. There may or may not be a child
there depending on max/min spare servers. A child is a process or a
thread that handles requests. A connection is a link between a client
and a child which resides in a slot.
In this case there is 1 request from the connection to a child which
has served 10,216 requests which is residing in a slot which has
served 15,022. The difference between the last two of ~4,800 requests
are requests to that slot which were processed by a child (thread or
process) which was subsequently terminated. Child termination can
happen because max spare servers was exceeded or for any number of
other abnormal reasons (process crashing). There may be other normal
reasons such as max number of requests per child.

Hi,
I've recently been pouring over some server status pages, and I am
trying to understand what the difference between a connection,
child and
slot. In particular, referring to the "Acc" column, which is the
"Number
of accesses this connection / this child / this slot".
Example "Acc" data for the homepage of our intranet is as follows:
1/10219/15022
I'm pretty comfortable with what a connection and a child is, BUT...
What is a "slot"? And what do they really mean when they refer to an
"access"?
Any pointers would be appreciated?
Cheers, Craig
