I have tested and cannot reproduce this. I think it is a local problem
on your system(s).

You could try:

cat iplist.txt | parallel -uj1 'ssh -qtt {} "sudo /usr/sbin/userdel
-rf abcuser " '
cat iplist.txt | parallel --tty 'ssh -qtt {} "sudo /usr/sbin/userdel
-rf abcuser " '
cat iplist.txt | parallel --dry-run 'ssh -qtt {} "sudo
/usr/sbin/userdel  -rf abcuser " ' > /tmp/foo
bash -x /tmp/foo

How small can you make iplist.txt and still get the issue? Can it just
contain localhost?

To debug the problem it is very important to be able to reproduce the
error. Therefore I would like you to reproduce the problem on one of
the virtualboxes from
http://sourceforge.net/projects/virtualboximage/files/
