Ok, thanks for info. I tend to think that it's kernel problem
with sendfile(2) and unix sockets.

Could you please test if a) not using sendfile (in location in
question) resolves the problem and b) not using unix sockets
resolves the problem? Just to make things more clear.

I'll try to reproduce this issue here and dig further into it, but
unfortunately I'm a bit busy now and it's unlikely to happen
anytime soon.
