Hi Heiler,
Yes, I know it. I just tried to answer to the following question.

The config option 'range_offset_limit none' (or -1) forces exactly that
behavior. It fetches whole object from the beginning to the end on
first range request. The problems you have encountered are consequences
of the bug 4469 you reported. I encountered the same problems using
Rock store. UFS/AUFS stores are not affected by the bug.

So, to fix the problem more quickly, the best way is to provide to
developers more information. For example, full debug log (ALL,9) for
isolated requests.

Thanks. Garri
