Hi John,
It looks like the threads are waiting on a dead thread...
I stuck this in uthread_info:
for (pthread = _thread_link_list; pthread != NULL; pthread = pthread->nxt) {
/* Find the state: */
for (j = 0; j < (sizeof(thread_info) / sizeof(struct s_thread_info)) - 1;
j++)
if (thread_info[j].state == pthread->state)
break;
/* Output a record for the current thread: */
sprintf(s, "--------------------\nThread %p (%s) prio %3d state %s
[%s:%d]\n",
pthread, (pthread->name == NULL) ? "":pthread->name, pthread->
pthread_priority, thread_info[j].name,pthread->fname,pthread->lineno);
_thread_sys_write(fd, s, strlen(s));
------------------------
for (itr = 0; itr < PTHREAD_DESTRUCTOR_ITERATIONS; itr++) {
for (key = 0; key < PTHREAD_KEYS_MAX; key++) {
if (_thread_run->specific_data_count ) {
if (_thread_run->specific_data[key]) {
sprintf(s, " key %d lock %x \n", key, key_table[key].access_lock);
_thread_sys_write(fd, s, strlen(s));
}
}
}
}
