Every time I try to execute sudo su - or any other sudo command for this matter my server hangs, sometimes it take 10 mins to respond and sometimes it never does.
I checked /etc/hosts file which was configured correctly. I also checked /etc/resolv.conf file which looked good as well.
any suggestions?
I am running redhat 6.9
linux rhel sudo

Have you tried runningsudoafter you’re already root?  Does it still hang then?  If so, you might try runningstrace(or some similar program) on it.

When does it hang -- before asking for the password or after? (Also,strace sudo -ior so might be your friend, even if its output is daunting, because you can see what it's trying to do when it hangs.)

Had the same problem on Ubuntu 16.04 on a newly created openstack remote vm. sudo su hanged for many seconds, maybe up to a minute, before it either worked or not. When it worked it could be made quick and reliable by running this once as root:
echo 127.0.0.1 localhost $(hostname) >> /etc/hosts

The problem can reproduced when the hostname is changed , edit your /etc/hosts by adding the output of echo $HOSTNAME after 127.0.0.1:
127.0.0.1 hostname
