Bonjour,
J'ai passé massif sur mon programme, je joins le .ps généré.
Je travaille sur Linux avec TSP.0.8.3 avec patch bug 19706
Je suis en train d'essayer de créer un programme qui ferait seulement du tsp
(même utilisation que le code de mon projet qui pose problème) et voir si le pb
se reproduit; dans ce cas, je vous ferai parvenir ce code...

Je vais ajouter de quoi STRACER les allocations des RINGBUFs
d'ailleurs je pense qu'on pourrait avantageusement remplacer
tous les malloc/calloc par un tsp_alloc de façon à pouvoir
maîtriser/monitorer toutes les allocations dynamiques via une seule
fonction de la lib TSP.

C'est possible.
Je m'en vais ajouter un mlockall histoire de voir si ça me pète à la tronche.

Oui, possible.
J'avais déjà limité la taille de certains buffers à 2 Mo.
https://savannah.nongnu.org/bugs/index.php?16629
Je vais voir ce que je peux faire pour le ringbuf.
Ce qui est étonnant c'est qu'un deuxième tsp_sample_request_init
stoppe le phénomène.
Mais bon ce n'est peut-être qu'un épiphénomène.
