Affected Product(s):
BIG_IP_NEXT(VE/HW) GTM
Known Affected Versions:
20.1.0, 20.1.1
Opened: Jan 30, 2024 Severity: 1-Blocking
GSLB Engine loses connection to another GSLB Engine Peers in a GSLB Sync Group and fails to reconnect.
The affected connection appears in a "half-open" state where one peer considers the connection open, another peer considers the connection closed and disconnects it every 10 seconds. As a result, GSLB Engines in a GSLB Sync Group have states of connections completely unsynced which results in the inability to distribute monitoring resources between each other and share statuses of resources.
When a GSLB Engine gets a certificate rotation, reboots, or experiences a temporary network issue that causes disconnection to another GSLB Engine Peers in a GSLB Sync Group, that connection can be not restored.
Once any GSLB Engine in a GSLB Sync Group gets certificate rotation or reboots, all GSLB Engines in the GSLB Sync Group need to have re-created configuration for all non-local GSLB Engine Instances.
