[Discuss-gnuradio] why "usrp2::tx_raw: FIXME: short packet" still appear

Hello all,
I tried 'ofdm example' on my two computers. I used 'benchmark_ofdm_tx.py' and 'benchmark_ofdm_rx.py' for test.
1. If I use computer A as transmiter and computer B as receiver. The transmission is successful.
2. But if I take B as transmitter and A as receiver. B will report 'usrp2::tx_raw: FIXME: short packet' sometimes.
3. And if B transmits in discontinuous mode, the error 'short packet' disappear but the signal transmitted out still seems not correct since A cannot demodulate it correctly. Some data may be lost at the transmitter side. (Later, I'll open logging to confirm this.)
I had a look in the discussion list and I found this error should have been fixed in gnuradio3.2.2. But at that time computer B used gnuradio3.2.0. So I reinstalled gnuradio for version 3.2.2. But this error still appears.
A computer is FC8 + gnuradio3.2.2
B computer is FC10 + gnuradio3.2.2
What does other configuration need to make the ethernet port work well?
Thanks a lot for your help!!
Best Wishes
