I have 18,102 RRD's, 17,671 of which are controlled by the hobbitd_channel
(the others are written/populated from other sources)
The slice I have the data on has a busy% between 16-88% depending on what's
going on (so yes, high I/O as well)
Iostat -xtc 5 2 :
device r/s w/s kr/s kw/s wait actv svc_t %w %b
sd20 382.6 217.2 2863.0 265.4 0.0 2.4 4.0 0 87
device r/s w/s kr/s kw/s wait actv svc_t %w %b
sd20 138.7 108.0 1304.1 605.9 0.6 2.6 12.7 1 31
So I would be interested in your solution ;)

It shouldn't do that normally, but I have seen some cases where it does that
when the hobbitd_rrd process cannot keep up with the amount of updates being
fed into it.
How many RRD files do you have ? Could you check if this server has a high
I/O load ?
If that is the problem, then I probably do have a solution ready for you
(I've run into the same problem at work).

Henrik
