Note that "-ssi" takes 2 parameters; I think you are missing the "1"
value to the boot_rsh_ignore_stderr token:
lamboot -v -ssi boot_rsh_ignore_stderr 1 hostfile
And therefore the "hostfile" argument is being ignored (i.e., taken
as the non-sensical value for boot_rsh_ignore_stderr SSI parameter).

This means that rsh is falling back to a different protocol to
login. Perhaps you might want to try a different service, such as ssh?
You can set which agent LAM uses (rsh vs. ssh) at run time -- see
