Only one SFlow Collector can receive data?

Hello,

I have configured two SFlow collector at 8132F

However, there only first one (Receiver Index 1) can receiving SFlow, the another cannot.  How to config both (all) collector can collect SFlow at the same time?

My sflow config is like below

-----

sflow 1 destination owner 1 notimeout
sflow 1 destination 192.168.1.106
sflow 2 destination owner 2 notimeout
sflow 2 destination 192.168.1.107 6344

----

Thanks!
