Suresh Marru commented on AIRAVATA-1417:
----------------------------------------

We should try and reproduce this and verify. An example will be to invoke a command with long
sleep.

> This can occur if there is a problem on the resource side that prevents the command from
completing.  For example, SSHing to a remote resource to run submit a SLURM script using the
sbatch command can hang if the sbatch command doesn't return.
> In these cases we may want a timeout to clean up these hung connections.  I suspect it
will be a significant problem if it occurs at scale (many jobs being submitted that don't
return).
