USRP locks?

Hi,

I experience some problems with my USRP and the RFX2400. When I run a
simple program to capture data samples from the USRP it locks after
some time (minutes to hours). There is no crash, it just stops
receiving samples. I attached the code to this email so others can try
it out to see if it is my setup or not.

The program is very simple. It configures the USRP and sends the
samples to /dev/null. I modified the file sink to inclue a counter so
I can see if there are samples coming from the USRP or not. The diff
is here:

Index: gr_file_sink.cc

RCS file: /sources/gnuradio/gnuradio-core/src/lib/io/gr_file_sink.cc,v
retrieving revision 1.4
diff -r1.4 gr_file_sink.cc
57a58

d_counter = 0;
123a125,126

141a145,148

d_counter += 1;
if (d_counter % 10000 == 0){
  fprintf(stdout, "count %d\n", d_counter), fflush(stdout);
}

I have the latest CVS/SVN version and use python 2.4.

Any ideas what could be wrong?
