Bug ID 1623645: The CWC retry connection is blocked.

Last Modified: Apr 28, 2025

Affected Product(s):
BIG_IP_NEXT(SPK) SPK(all modules)

Known Affected Versions:
1.7.9

Fixed In:
1.7.10

Opened: Aug 05, 2024

Severity: 2-Critical

Symptoms

During the upgrade from version 1.7.8 to 1.7.9, the CWC pod successfully connected to RabbitMQ but quickly lost the connection. This caused a race condition where the system's logic for starting and stopping a process got out of sync. When the connection dropped, the system tried to stop a process before it had even started, leading to an error that blocked further actions, including the attempt to reconnect.

Impact

CWC is not able to retry communication with RabbitMQ.

Conditions

The RabbitMQ pod was immediately restarted while the CWC pod was still booting up.

Workaround

Restart CWC pod.

Fix Information

Ensure that communication is synchronized across all channels.
