Paul, I read that as lack of available shared memory. I'm curious what result you get if you run the following at the command line: sysctl kernel.shmmax
Not sure how you installed gnu radio, but if you used Marcus's build_gnuradio script then the following changes should have been made in /etc/sysctl.conf: # Updates for Gnu Radio net.core.rmem_max = 1000000 net.core.wmem_max = 1000000 kernel.shmmax = 2147483648 These would be considered good starting values for general GNUradio with a USRP work. You can experiment at the command line to see if it solves your issue with: sudo sysctl -w kernel.shmmax=2147483648 -Ian On Nov 21, 2013, at 3:17 PM, Paul B.
