We have also seen this happen.

Pseudo tty is reserved so, that when logging in it appears to be in raw
mode although stty says it is normal.

Using newline I am able to log in but all characters get mapped to EOF so
it does not help, as I get immediately logged out.

But when user with tcsh as login shell logs in, pseudo tty appears to work
ok.

And everytime this happens, there has been background processes on that
line.
