Если pthread_create() возвращает NULL в create_thread(), то triton_context_schedule() вываливается в корку, например, так:

pthread_create() возвращает в ошибке EAGAIN. Я почитал, это может быть из-за очень большого размера стэка для тредов (по умолчанию в Gentoo это 8 МБ, например: 8 МБ * 350 тредов = 2,8 ГБ памяти при 1000 сессий). Поэтому, может, стоит сделать в create_thread() что-то типа этого:
pthread_attr_t attr;
pthread_attr_init(&attr);
pthread_attr_setstacksize(&attr, PTHREAD_STACK_MIN); /* или побольше, например, 256КБ */
if (pthread_create(&thread->thread, &attr, (void*(*)(void*))triton_thread, thread)) {
...
