[slurm-users] spank plugin parameter max length ?

[Tueur Volvo]

Hello, i create spank plugin and i have a problem.
With my plugin i create new parameters --hbm

If i write srun command it's work
srun --hbm="tototututititatatetetyt" hostname

but if i add 1 caractere, my slurm job "freeze", job is in R status
srun --hbm="tototututititatatetetyty" hostname

So maybe slurm have limitation number parameter length ? max is 23
caracteres, why ?

In my code, slurmd call slurm_spank_init and _script_opt_process and
slurm_spank_task_init
but when i have my error slurmd not call slurm_spank_task_init

this is my code :

#include <sys/types.h>
> #include <stdio.h>
> #include <stdlib.h>
> #include <unistd.h>
> #include <string.h>
> #include <sys/resource.h>
>
> #include <slurm/spank.h>
