Default, I didn't define anything. Don't even know how to.

There are no prolog/epilog defined.

It keeps looping through these messages. Is it normal?

And the opened shell is idling?
How do you log in by this method – the default "builtin" method or anything
self defined?
In my clusters I can't observe this behavior.
Even if there would be something running in any of the shell's profile: it
should show up for the opened shell but not for the sge_shepherd which runs
under the sge admin account.
Any global or queue prolog in place, which is supposed to run under the sge
account?

From the root account you can `strace -p 22443` and check what is going on
therein.
