strange problem in bridge mode

[Aadolf]

Hi
I used opnsense in my network for testing bridge mode.Our traffic was 10 Mbps or 12 Mbps after some hours(22 hours or more) my network interface for inbound traffic became unstable.I plugged cables to another interfaces(bridge members) at that time network traffic became well but after 4 or 5 minutes the new interfaces became unstable(up/down/up/down....) again you can see this in the file that i have attached here....

opnsense version 15.7.5
NIC chip-set =>Intel(R) 82583v chip-set
FreeBSD 10.2

Haven't seen this before, can you reproduce this on a recent 16.1? 15.7.5 is really old. :/
