Opened: Dec 19, 2024

Severity: 4-Minor

Symptoms

BIG-IP is unable to create a GRE flow, the connection fails to complete.

Impact

BIG-IP uses a duplicate translated call-id when communicating with the server, but there are no stats in the tmstat table to perform additional troubleshooting of the cause.

Conditions

This can happen for various reasons, for example: - CMP communication with another TMM failed. - Remote end (server) to which one client is already connected, responded with a call-reply containing a call-id which was already used by that server in a previous, existing(still alive) call setup. - BIG-IP uses translated call-id in the outgoing call request which was already sent to the server and the GRE connection for that setup is still UP, and validation fails when the server accepts a connection.
