Doc Type: Enhancement
Doc Text:
Feature: Added reconciliation job which periodically cleans up stranded IP addresses. Reason: Sometimes IP address allocations with Whereabouts are left stranded due to cluster events such as reboots, which don't allow the CNI DEL to process in order to properly release an IP address. When pods that reference Whereabouts IP-managed secondary interfaces use ranges that are exhausted due to too many stranded IP addresses, these pods can wind up in an irreconcilable crashloop. Result: Stranded IP addresses are periodically cleaned.

Hello Team,

I have another customer with the same issue in RHOCP 4.11.6 --> 03412816

Please, could you confirm if the bug was also backported to 4.11?

Many thanks in advance,

Best Regards,


Adrián.
