There is capacity limit on egressIP for different cloud provider, for example, GCP, the limit is 10.
If the number of egressIP added to hostsubnet exceeds the capability limit, it is expected some logging message is emitted to event log, that can be seen through "oc get event"
On a GCP with SDN plugin, configure egressCIDRs on one worker node, configured 12 netnamespaces, each has 1 egressIP configured, the total number of egressIP for the hostsubnet has exceeded its capacity limit of 10. No event log was seen to indicate that the number of egressIP for the hostsubnet has exceeded the limit.
$ oc get clusterversion
