Hi Janna;

It sounds like a Arp cache table problem to me. If your slurm head node 
can reachable ~1000 or more network devices (all connected network 
cards, switches etc., even they are reachable by different ports of the 
server), you need to increse some network settings at headnode and 
servers which can reach same amount of network device :


Also some advices for big cluster at slurm documentation:
