Be sure to run yum clean all to dump the update cache.

If the error message is claiming  a full /home dir (which is why users
can't log in), so someone hosed the home dir by filling it up. 

for user in `ls -1 /home`
echo "$user `du -ks $user`"

will print a list of the space used by user in the /home folder.

37GB is a small drive system these days. 

It is usually a good idea to implement quotas on a multi-user system to
prevent a user from blowing up the drive space.
