Opened: Jul 31, 2018

Severity: 3-Major

Symptoms

Mcpd crashes after a config sync.

Impact

Mcpd may take too long to validate the APM configuration and is killed by watchdog, causing a core

Conditions

This can occur during configuration validation when APM is configured.

Workaround

Use the Visual Policy Editor to configure access policy instead of tmsh commands. The Visual Policy Editor does not allow policies to be created if they contain loops.

Fix Information

Fixed an mcpd crash related to policy loop detection in APM.
