A dozen or so idle processes is perfectly normal for prefork (which
you are clearly running, BTW). Only worry about this if there are a
consistently high number of idle processes (say 30 or more for a lightly
loaded server) in which case you can tune the value of MaxSpareServers
to suit.
Have a read about the prefork MPM in the documentation:
http://httpd.apache.org/docs/2.2/mod/prefork.html
If the number of idle processes is consistently higher than
MaxSpareServers you have a bug.
HTH,
Pete
