Three years ago, I used to run my USRP1-based radio astronomy software for months at a time
with no issue.
In the last year or so, I've been unable to maintain those kinds of uptimes with either USRP1 or
USRP2, which I ascribe to fundamental changes in Gnu Radio, but I haven't been able to put
my finger on exactly which flow-graphs will "wedge" after a few days, and which ones will
keep going and going. I have one flow-graph that uses the USRP2 at low bandwidths (400Ksps
or so) that seems to be able to run forever. Another, similar flowgraph, will tend to "wedge"
after a few days.
I also have a flow-graph that uses an ALSA source and sink, and it can only run for a few
days before "wedging".
I think the USRP *hardware and drivers* are perfectly capable of running forever, but the
current Gnu Radio seems to have issues that I haven't been able to pin-point with long-running
