when we reboot node or restart NetworkManager(systemctl restart NetworkManager) we are loosing some of the ovs interfaces (randomly, not on all restarts).
logs are here:
Missing interfaces:

In this particular instance of run, we lost two interfaces.
we have a script which sets "autoconnect-slaves" to 0, which was introduced for an older version of NM. grep -lF -e type=ovs-bridge -e type=ovs-interface -e type=ovs-port /etc/NetworkManager/system-connections/*|xargs -I % nmcli connection modify filename % connection.autoconnect-slaves 0 this scripts also runs currently, that why all "autoconnect-slaves" set to zero.
when we are losing interfaces that port additions are not coming to ovsdb:
2022-08-26T22:38:26.176Z|00179|bridge|INFO|bridge data_bridge: added interface traffic5_iface on port 1
2022-08-26T22:38:26.348Z|00182|bridge|INFO|bridge data_bridge: added interface traffic1_iface on port 2
2022-08-26T22:38:26.376Z|00183|bridge|INFO|bridge data_bridge: added interface bm25c_ext_iface on port 3
2022-08-26T22:38:26.376Z|00184|bridge|INFO|bridge data_bridge: added interface bond0 on port 4
Only 4 interfaces are getting added back, two are missing, "ovsdb-tool -mmmmmm show-log " shows the same.
Any pointers where it is going wrong?
