No problem running batch and interactive jobs on the same nodes. Judging from the error message: srun: error: Task launch for 442.0 failed on node svthwVCS: Invalid job credential
The job credential includes the node name(s) that it is valid for. I would guess there is some problem with the naming of nodes.
