Severity: 2-Critical

Symptoms

On an unlicensed system with a built-in iRule attached to a virtual server, mcpd might crash.

Impact

On an unlicensed system, mcpd might crash repeatedly.

Conditions

-- Unlicensed system (including as a result of the service agreement check date validation treating a license as invalid). -- At least one built-in, system-supplied iRule is attached to a virtual server. -- mcpd loads from the config files, such as when having just upgraded.

Workaround

Perform the following procedure: 1. Reactivate the license on the system from the command-line, following the instructions in K2595: Activating and installing a license file from the command line :: https://support.f5.com/csp/article/K2595. 2. License the system. Note: Running commands (e.g., tmsh show /sys hardware) on VIPRION systems while mcpd is down might fail or otherwise not work as expected.

Fix Information
