Hi everyone,

I could solve this problem like this:

First: read the rows and columns of your raster map using r.info. Appropiate
sample intervals are obtained by dividing that number by 100. 
For example, if you have:
Rows:         7603                                                       
Columns:      8556  

Good sample intervals are: 76,86

So, set up your region to match one of the raster maps that you are using
(if you defined a group it can be any of the maps in the group), for this
use g.region.

Now you should be able to run i.cluster with the sample intervals = 76,86.

Worked for me.
Here you can find more info regarding this topic, it is very helpful even if
you are ussing another version of GRASS:
