I have installed tripleo openstack version rocky containerized with Undercloud in virtual platform and 3 controllers and 2 compute Baremetal.

My whole setup is running  on centos7.

Overcloud cluster start failing once number of networks in overcloud reach more than 70. Lots of resources failure issue shown there. I don't know why HA cluster failed after 70 networks in OC.

Is some kind of threshold in tripleo configuration? so it is restricted not to create more than 70 or 80 netwoks. How could i fix this?

I did not see such issue when I am using redhat platform and it's repos. This issue coming in opensource repos on Centos 7 . Please help how to fix this issue so I can scale up my openstack upto 2000 vms in this situation it's not possible.
