Normal to have 14 httpd processes?

The HTTPD server uses separate processes for each client
connection.
When the client's request is received by the server is uses
one of
already running idle processes of the server. If there is no
idle
processes (all running copies of the server are serving
clients) the
server will fork another process to service the request.
When the
request is serviced the server process used for that request
will become
idle and awaiting a new request. Of course, there are limits
on the
number of server processes, e.g. the server will not use
more than
specified number of processes and will kill the idle
processes when
there are too many server processes. The process owned by
root is the
master process which control creation and deletion of server
processes
and the processes owned by apache are the ones used for
processing of
client requests. The limits are set by directives
StartServers,
MinSpareServers, MaxSpareServers in Apache configuration
file.
Therefore, if the number of httpd processes is within the
limits set by
those directives it is normal. You may lower the limit the
number of
httpd processes using the directives above.
