Hi everyone,
I want to test something with usrp running continously under
normal environment.
Can someone tell me the real data of how long usrp is capable of
running continously.
Thanks.

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
applications.
