@rapopesc I’ve run the a script with 1000x locally unmounting/mounting cvmfs without autofs, never triggering the issue.
@asevcenc that is really curious, we have in fact switched to job_container recently, I will further investigate this. I found it hard to debug as it does only happen seldomly. Still, I’ve never seen it on the login nodes where there are no slurm jobs running (and no mount namespacing)
