as it said in https://bugzilla.redhat.com/show_bug.cgi?id=2112111#c6

it is very difficult to reproduce, I tried the script as below:use the topo in case:kernel-kernel-networking-openvswitch-ovn-regression-bz1776712_broadcast_limit.noarch
ovs-vsctl set open . external_ids:ovn-ofctrl-wait-before-clear=5000
ovs-vsctl list open_vswitch .
sleep 5
for i in `seq 100 200`;do
        systemctl restart ovs-vswitchd
        sleep 1
        ovn-nbctl lb-add lb$i 2.2.2.$i 10.1.2.$i -- ls-lb-add s1 lb$i
        sleep 5
        count=`ovn-appctl -t ovn-controller group-table-list | awk '{print $2}' | sort | uniq | wc -l`
        if [ $count == $i ];then
                echo $count
        else
                echo $count
                break
        fi
        if [ `cat /var/log/openvswitch/ovs-vswitchd.log |grep error` ];then
                break;
        fi
        sleep 10
done

no errors found.

version:
# rpm -qa|grep ovn
ovn22.03-22.03.0-95.el8fdp.x86_64
ovn22.03-host-22.03.0-95.el8fdp.x86_64
ovn22.03-central-22.03.0-95.el8fdp.x86_64

set as verified.
