Hello,
I am running a script on ROACH-2 boards that writes and reads a particular
register (ex: acc_len). After 31 or more write/read commands I consistently get
the following errors:
Exception in thread Thread-254:
Traceback (most recent call last):

(msg.name, timeout))
RuntimeError: Request read timed out after 10.0 seconds.
The issue is resolved by restarting the script and creating new katcp client
connections with the ROACH-2 boards.

Any help or suggestions would be very much appreciated!
