My php script   exec("sudo /usr/local/bin/setpassword $uid $pass"); hangs,
so I did  #ps -ef |egrep 'nobody|sudo' and I get these:

I dont't know why the last line above is running as root. It should be 
nobody. Because apache is running as nobody.
The sudoer file has a line like     nobody  ALL= (ALL) NOPASSWD: ALL
and another line like  root    ALL= (ALL) ALL

So when I login as root and test sudo command, it hangs. Everything was 
fine before.
Also when I login as root and run command: strace sudo ls, it hangs at 
the last line below:
