Seems like there's stuff causing httpd to crash and hang. Before
starting httpd again you need to kill the hanging processes (ps
aux|grep http or lsof -iTCP:80).
What exactly are you serving off that web server? Do you have any
manually installed/compiled programs (e.g. php) or from 3rd party
repos?
