Hi, Jeff,
That sounds like a weird one! Here are some ideas to try:
1) Check the output of dmesg on the roach2 after the problem occurs.
2) Watch the network traffic between the problematic machine and the roach2
using

Thanks a lot!

The working one has lots of interleaved connections. Can you make
sure that everything using katcp is off, then start capturing, then

= corr.katcp_wrapper.FpgaClient('10.0.0.200', 7147, timeout = 60),
fpga.is_connected() always say False. Here's some clues:
