d pipes with no problems. I'm not sure if the problem is the
tcp control or a lower level of gnuradio.
Any suggestions??

Is there a way of sending the data from the USRP to another application
using pipes?? I only know the basics of pipes, and need to look into it
more. I was going to try using TCP but thought pipes maybe easier. Also,
labview (the app i am sending it to) expects data over the TCP port to be in

Some more information and possible solution (it's been running for about 20 minutes now without any
problems and it usually failed in less then a minute).
I am transmitting using 4 DACs at 1MS/s and receiving using 4 ADCs at 1MS/s.
When the problem occurs:

Hi,
i think i just hit the same issue

Eric,
Have you made any progress with this?
I'm having a problem that may be related. The blocks are layed out like this.
USRP Rx -> ... -> pipe
gr_sig_source -> ... -> USRP Tx
When running in gdb:
1. I wait for it to lockup
2. hit Ctrl-Z (to get into gdb)
3. type continue
4. more data is pro

This is a curious behavior: if
1) Use a vector source at the head and the USRP at the tail all is OK
2) Use the pipe fd source at the head and a file sink at the tail all is
OK
but if
3) Use a pipe fd source at the head and the USRP (with a parallel file
sink to monitor) at the tail data very s
