[slurm-users] Cannot run interactive jobs

CentOS 7.7.1908
Slurm 18.08.8

When trying to run an interactive job I am getting the following error:

srun: error: task 0 launch failed: Slurmd could not connect IO

Checking the log file on the compute node I see the following error:

[2020-03-25T01:42:08.262] launch task 13.0 request from UID:1326 GID:50000 HOST: PORT:14980

[2020-03-25T01:42:08.315] [13.0] done with job

When doing the same on a CentOS 7.3 and Slurm 18.08.4 cluster the interactive job runs as expected.

Any advise on how to remedy this would be appreciated.
