USRP sending packets after closing application

Hi list,

I notice that after running any application (for example uhd_fft), the
USRP
continues to send a lot of packets to my machine. Is there something I
am
missing ? Maybe the application is not closing correctly and stopping
the
USRP from sending packets.

Thanks.

Are you seeing that LEDC is left on?

Basically, if the device is not cleaned up properly, like the app is
just killed, when in continuous streaming mode, the device will continue
to stream.

However, usually this closes the sockets, the kernel then sends a ICMP
destination unreachable to the USRP and the USRP FW shuts down the RX
DSP.

Perhaps that isnt happening or something is still running in the
background?
