Hi, Kang:
In the few day, we try to create more vbrg and vgw for test onap performance.

In our onap and vcpe envirnoment, we had created a success vxlan tunnel for a pair of vbrg and vgw0 instance, and we had created about more than 44 vbrg instances that can be see by use "select * from DHCP_MAP;” in sdnc docker database. So we create most vgw instance almost error for this reason “Received error from SDN-C: Error updating md-sal for tunnelxconn-allotted-resource”, and we didn’t attention to this at first.

So, we delete all vcpe use case data like vcpe stack, instance, keypairs(in openstack almost 95 keypairs), SDNC database DHCP_MAP table record, data in __var file and data in __tmp file.

After all delete, we run vcpe.py infra success. We run vcpe.py customer before we confirm the vbrg running vppctl and the mac address had to insert into DHCP_MAP table, BUT, the error happened again “Received error from SDN-C: Error updating md-sal for tunnelxconn-allotted-resource”.

We check SDNC’s karaf.log and SO’s errormso.log, we found the error not be same of the desciption for https://jira.onap.org/browse/TEST-108.

The error log some message show as blow:
