logs warning message down all the port of switch chip2 on CCR 2004 16G

Dear all Experts,
I have a CCR 2004 16G.
I am facing an issue I have 2 bridges and two DHCP servers on both bridges.
bridge-1 I have DHCP server 172.16.0.1/16 port-16 trusted=yes port-15 trusted=no
Bridge-2 I have DHCP server 192.168.100.1/24 port-13 trusted=yes port-14 trusted=no

I connected both interfaces 15 and 14 with ethernet wire.
for a special purpose. (for )
I received a Bridge warning message in the logs of DHCP it’s due because I have combined 2 DHCP servers with an ethernet wire.
but I don’t know after a few time all ports of Switch Chip 2 which consists of 8 ports goes down and up after a few seconds. and disconnect my whole network for a moment.

why are ports going stuck or down

Because of misconfiguration.

May I suggest to aggregate all “your problems” into a single topic?

yes please
