The option -c is the short form of --cpus-per-task, which really means "cores per process". As you only have 16 cores per node, you can't run a single process on 17 cores. You probably want srun --ntasks=17 --pty bash I'd suggest you use the long forms of the options until you get more familiar with Slurm (although even that can still be confusing, cf. core/cpu, task/process).
