Hi John and Jo-Philipp, Have you ever got similar problem, or known any possible reason about this, or known anyone who probably know this?
I just found much memory would be consumed if I configured board as bridge mode in /etc/config/network and did UDP throughput test. But using brctl to configure bridge mode didn't consume memory. Thank you very much. Best regards, Yangbo Lu > -----Original Message----- > From: Y.B.
