Hi, good holidays, there ?
I have applied the patch below.
It works now:

padbr345P -O rmgr=slurm  --proc-summary  -a

I'm just running out of the door myself and will be away until Sunday
now.

ranks 3 and 6 are on the same node as rank 0, can you try the following
additional patch which should cause it to skip over the mpirun process
and look for local ones based on their environment.

If this patch doesn't work take a look at the the contents
of /proc/$pid/status for the process it's erroneously reporting as rank
0 to see what Name is set to.  In the example you sent it's pid 22210
