Thank you Sylvain.
I thought 900 ksps was one of the standard rates in the RTL2832 chip, so
that's why I used it, to keep cpu usage low because my application must
work in a Intel Atom N270, the smallest one.
In fact I used many times 900ksps with GNURadio 3.6.x without any problem
at all.
I'll use 1Msps for now.
