Came up with a solution myself just now. The problem seems to be that only those contacts that should exist in both simulations (original and restart) are to be defined with the "_ID" option in the contact card. Prior I had used "*CONTACT_AUTOMATIC_SURFACE_TO_SURFACE_ID" for all contacts in the original simulation. Not mentioning all the IDs in the restarted simulation resulted in the job not being submitted properly. Now I use "*CONTACT_AUTOMATIC_SURFACE_TO_SURFACE" for all contacts that are not carried over to the restart simulation aswell as those that are newly created in the restart simulation. Everything works as expected. 

Maybe the dodumentation should be somewhat updated if this problem is not limited to my specific model/machine/version. The way I understand the excerpt above it is not clear that I have to reuse all contact IDs that are defined in the original model.Â
