[slurm-users] "Plugin is corrupted" message when using drmaa / debugging libslurm

I'm facing a weird issue where launching a job through drmaa 
(https://github.com/natefoo/slurm-drmaa) aborts with the message "Plugin 
is corrupted", but only when that job is placed from one of my compute 
nodes. Running the command from the login node seems to work.

My cluster runs Slurm 20.11 and the issue appeared when it was migrated 
to that version or the version before (19.05). It is hard to tell 
because the two updates were very close.

Anyway, the message seems to originate from libslurm36 and I would like 
to activate the debug messages (debug3, debug4). Is there a way to do 
this with an environment variable or any other convenient method ?

I'd like to follow where exactly it fails since I compared Slurm 
libraries on the compute nodes and on my login node and couldn't find a 
difference. Strace didn't yield anything interesting either.

Thank you,
J.C. Haessig
