cache file has too long header (bug) ?

Hi Maxim,

    Thank You for your answer. It really makes sense, however, in the
mentioned case, I could see an elevation of  the number of occurrences just
after the migration from nginx 1.6 to nginx 1.8. 
    This behaviour affects < 0.2 % of our requests, but it means hundreds of
requests per hour. 

    Also, I could see this implementation isn't new, therefore I believe
this behaviour maybe another change caused it to start happening.

    Regarding your comment about the race condition, most times the object
the caused the message appeared only once on the access log, so I don't
think it was caused by a concurrency.


Best Regards,
Biazus
