Thanks for your answers. It's OK adding maxinput (I would suggest to add this parameter in the default config).
Then, I ran into another problem... When a package is added, LORS creates 4 temporary text files (under /tmp), and they are not removed when the procedure is completed. If another server attempts to run the same procedure, he gets a "permission denied" error... I think it would be better to generate unique file names to avoid this sort of collision.
