OCI Instances Lose Network Connection Every 24hours Due to the DHCLIENT Not Renewing The Leasing. (Doc ID 2651795.1)

Last updated on JUNE 15, 2023

Applies to:

Oracle Cloud Infrastructure - Version N/A and later
Information in this document applies to any platform.

Symptoms

OCI instances lose network connectivity every 24 hours,  by default when the dhclient is started it runs for 24 hours, that is  the lease time this means 86400s when this period expires it is not able to renew it again as a result the IP is not assigned to the interface  and network is lost.

In order to recover the network connection for  another 24 hours, the instance needs to be rebooted or the dhclient service needs to be killed and started.

 

This is the lease time for dhclient.

 

Changes

There were some additional ifcfg-x files  added on the /etc/sysconfig/network-scripts/ directory which are not part of the original configuration for OCI.
