I replaced "!=" with "=!=" in the APPEND_REQUIREMENTS-expression and now
everything works fine, thank you so much!
But, I don't understand why this helped me out. I'm still convinced that
there must be some inconsistency with the dagman and APPEND_REQUIREMENTS. As
I said, when I submit 'normal' jobs, I don't need the "=!=" in the
APPEND_REQUIREMENTS-expression, just for the dagman.
Correct me if I'm wrong, but as far as I understand, "A=!=B" means that this
expression is only compared, if A is defined. I swear, subnet is defined on
every machine, that's a standard condor setting. (By the way, I tried
APPEND_REQUIREMENTS=Mips>1000 to check, if there is a problem when
APPEND_REQUIREMENTS is too long, but this didn't work either.)

Do you have any idea?

Kind regards,
Thomas Bauer
