--- Comment #2 from jhkim <jhkim at growthsoft.co.kr> ---
(In reply to Sanoj Unnikrishnan from comment #1)
> Is this scenario reproducing?
> 
> Looks like a segfault in qr_readv_cached function. 
> Did u get a core dump/ can u share it? 
> Could you generate a core and share the core file for further analysis?
