Description of problem:
Deployed dual stack hub cluster (IPv4 and IPv6) , Cluster gets deployed and ready . After 18 to 24 hours master nodes goes not ready state . The infra machine can't reach br-ex interface either through IPv4 or IPv6 address. Logging into console of master-0 the br-ex interface lost both address. performing nmcli connection down/up br-ex the interface timeout get ipv4/ipv6 address. The NIC 100G -card used (Intel Corporation Ethernet Controller E810-C for QSFP (rev 02) workaround: reboot node , The ipv4/ipv6 address get assigned to br-ex interface. Note : The DHCP/DHCPv6 lease refresh is working properly.
Version-Release number of selected component (if applicable):
4.12.0-0.nightly-2023-03-01-040753
How reproducible:
Always, every 18 to 24 hours run time
Steps to Reproduce:
1.Bring dual stack hub cluster 4.12.0.0 nightly build 2.Monitor nodes are in ready state after 24 hours 3. The nodes go to not ready state 4.[kni@infra6 ~]$ oc get nodes NAME STATUS ROLES AGE VERSION master-0.slcm.nokia.bos2.lab NotReady control-plane,master,worker 26h v1.25.4+18eadca master-1.slcm.nokia.bos2.lab Ready control-plane,master,worker 26h v1.25.4+18eadca master-2.slcm.nokia.bos2.lab Ready control-plane,master,worker 26h v1.25.4+18eadca
Actual results:
Nodes are 'NotReady' state and lost ipv4 and ipv6 connectivity
Expected results:
Nodes are up running always and reachable through ipv4 or ipv6 network
