Have you tried running the "restart-httpd" command as the Nagios user 
from the console?
Also, on my server Apache (2.2) takes roughly 3-4 seconds to start up, 
and it looks like Nagios doesn't provide any delay between running the 
event handler, and the subsequent check if httpd's running.

If the command works OK, try adding a "sleep for 5 seconds" command 
(e.g. "sleep 5" for bash) to your event handler script after Apache has 
started.
