[Discuss-gnuradio] Alternating runs of benchmark_tx.py with "S" errors |

Hello,
With a recent B100 and WBX card and using gnuradio 3.6.3, I'm getting
alternating normal runs of benchmark_tx.py and runs with many "S" errors. The
cycle then repeats. I'm using Ubuntu 12.10 with a 2.7 GHz i7 CPU.
The output of two runs of benchmark_tx.py is followed by the output of
uhd_usrp_probe
Any help would be appreciated,
Kevin
