This is a very strange error. It suggests a corrupted pdb file. Can you post
me the nuc.pdb file that you are trying to load and I'll take a look. Also
download the pdb from the link on the tutorial page and compare it to the
one you made by following the steps in the tutorial. They should be
identical.

This is almost certainly a problem with the pdb file. Try running xleap as
stated in the tutorial and type edit LYS - it should come up showing you a
lysine residue.

I take it all the tests before this passed. If they did then I wouldn't
worry about this test. You won't need sander.QMMM unless you want to run
QMMM calculations. You need to apply the bug fixes before you can use this.
You also need to increase the limits in your shell using the ulimit command.
For the moment I wouldn't worry about it.
All the best
