This is suspicious, for me too. But maybe there is some logic behind opening the same file many times.

I just have a small remark about your patch: Shouldn't you call close_files() here, too? (With a partially full fd_list array handled, of course)

+void * threads(void* thread_id_) {
+	int thread_id = (uintptr_t) thread_id_;
+	char errmsg[80];
+	FILE *fd_list[MAXFILES];
+	int i;
+
+	/* Open files */
+	for (i = 0; i < numfiles; i++) {
+		if (debug)
+			printf("Thread  %d : Opening file number %d \n", thread_id, i);
+		if ((fd_list[i] = fopen(filename, "rw")) == NULL) {
+			sprintf(errmsg, "FAIL - Couldn't open file #%d", i);
+			perror(errmsg);
