А можно ещё вот тут:

fr 0
p *p->busy->buf
p *p->busy->next->buf
p *p->busy->next->next->buf

И далее, увеличивая количество "next", пока ругаться не начнёт.

И аналогично для *p->out:

p *p->out->buf
p *p->out->next->buf
p *p->out->next->next->buf

Опять же, пока не начнёт ругаться.

Если удастся воспроизвести и получить debug log - будет
замечательно. Достаточно на уровне server и/или location.
