[Discuss-gnuradio] My app waits undefinedly after an O printf

[Pol Henarejos]

Dear list,

I am using gr_uhd_source as the source of my app. At some moment, there
is an overflow, an O is printf'ed and the scheduler stops. The program
is still running but there is no flow of samples between blocks. They
are waiting for something. I added the following lines in the work() of
gr_uhd_source

printf("no = %d\n", noutput_items);
if (_metadata.error_code != uhd::rx_metadata_t::ERROR_CODE_NONE)
        printf("Error %d\n",_metadata.error_code);

and the output, after some time, is

no = 4094
no = 4096
no = 4094
[...]
no = 4096
no = 4094
no = 4096
no = 4096
Ono = 4094
no = 2133
Error 8
no = 2133
Error 1

and here waits for some thing and no more printf take place. Be aware
that this happens when the O appears.

Anybody is expecting the same? Could you provide me some hint?

Thanks.
