Hi I made some progress trying to understand the problem i reported some weeks ago:
https://lists.schedmd.com/pipermail/slurm-users/2023-May/010027.html I noticed that the intermittent connection timeout that i am experiencing occurs only when using the tcp based direct connection to establish communication between stepd on different nodes. When disabling the optimized direct connection using export SLURM_PMIX_DIRECT_CONN=false the submission of hetjobs is stable and not connection timeout occurs anymore. Any idea what can goes wrong when using tcp based direct connection together with hetjobs?
