This is a fast-cgi configuration isssue in your Apache config file. 
I don't recall all the details, but there are options to the FasttCgiConfig
directive to control the minimum and maximum number of working
cgi's it should start, as well as controlling lifetime.  For a heavy-weight
process like MapServer I would suggest limiting it to two or three
worker cgi's at a time. 

You can also control lifetime of the cgi's so if you continue to see
some memory leaks, you might want to limit the lifetime to a couple
of minutes so they get restarted fairly often but not for every request.
