where is the alternate spawn code? I can take a look at this later this week to see about what's going wrong.

oh i see, that's kind of what @jtronge and i were thinking of doing then.

@dalcinl thanks for putting this together. Just to check you are not trying with these failures to run oversubscribed, correct?

I think i have a fix in prrte for the singleton problem: ``` python test/test_spawn.py -v ``` odd that you don't see the assert that I observed. I''m having problems...

I'm not sure why it is, but all of these related tests error out for me in the dpm cleanup code. Example with this one: ``` [st-master][[19684,1],0][btl_tcp_proc.c:400:mca_btl_tcp_proc_create] opal_modex_recv: failed with...

The test does not hang for me, nor show this issue with the DPM cleancode in the 4.1.x branch (which is effectively 4.1.6).

Interesting I don't see a hang but i get an error coming out the of the TCP BTL when using main. I also tried the patch in PR #12119 but...

I don't like that idea. python2 has been deprecated for years.

maintaining a script written in python2 would be a lot of overhead.
