Backend warnings retr/redis on stats page

[Graeme Donaldson]

Hi

HAproxy 1.4.8.

If I look at the stats page, on one of my backends I'm seeing these values
under the warning column: retr (344) and redis (172). The backend has 8
servers and only 1 has non-zero values for this column.

Can someone explain what the numbers mean, I've tried poking through the
documentation but nothing stands out.

Thanks,
Graeme.
