Severity: 3-Major

Symptoms

Tmm crashes when performing 'tmsh show sys connection' and there is a connection from a secondary blade to a CMP-disabled virtual server.

Impact

Tmm crashes and restarts impacting traffic.

Conditions

This occurs when all of the following conditions are met: -- There is a CMP-disabled virtual server, or a floating self-IP address defined. -- There is a connection to that server from the control plane of a secondary blade (this can include monitoring traffic). -- Connections are displayed that include the connection from the secondary blade ('tmsh show sys connection').

Workaround

Do not use 'cmp-enabled no' virtual servers when there will be connections from the BIG-IP control plane to the virtual server. Avoid using tmsh show sys connection.
