Occasionally during program exit with Open MPI SHMEM jobs, we are seeing
the following message:
srun: fatal: ../../../src/api/step_launch.c:1037
step_launch_state_destroy: pthread_mutex_destroy(): Device or resource busy
Our environment:
* 100+ node KNL cluster
* CentOS 7.4
* Open MPI 3.x (an interim kit between 3.0 and 3.1)
* Slurm 17.11.0
This was reported at <https://bugs.schedmd.com/show_bug.cgi?id=4333>
against a 17.11.0 RC kit, but we are seeing it now in the 17.11.0
released kit (I confirmed that Moe's fix appears in our sources). Has
anyone else seen this? Or better yet, has anyone found a way to fix it?
