Doc Text:	In previous RHOSP releases, connectivity disruptions could occur to IPv4 load balancers. This problem was caused during execution of a maintenance task for fixing an incorrect format used in the `ip_port_mappings` parameter on IPv6 load balancers. The task fixed the incorrect format on IPv6 load balancers, but also erroneously changed the `ip_port_mappings` parameter on IPv4 load balancers. + This issue has been resolved, and IPv4 load balancers no longer experience connectivity disruptions after the maintenance task is run.

Description Fernando Royo 2024-08-27 07:13:47 UTC

Description of problem:
Maintenance task fixing the IPv6 format in ip_port_mappings is clearing IPv4 format breaking LBs with health monitors.


How reproducible:
Not easy because that maintenance task is only triggered once on start up of the component so need to follow below steps to reproduce.

Steps to Reproduce:
1. Create a IPv4 OVN LB + Health Monitor
2. Restart octavia-driver agent and wait for the maintenance task to run


Actual results:
ip_port_mapping field of the LB on the OVN NB DB will be cleared after the maintenance task executing.

Expected results:
ip_port_mapping not modified after the execution of the maintenance task.
