Right after clicking the 'Apply Access Policy' link, APMD may generate a core file and restart; or appears to be locked up.


If APMD restarts, then AAA service will be interrupted for a brief period of time. If APMD appears to be locked up, then AAA service will be stopped until manually restarted.


-- Changing APM configuration, especially Per-Session and Per-Request Policy. -- Configured for AD or LDAP Auth Agent.



Fix Information

APMD now processes the configuration changes correctly during 'modify apm profile access <profile name> generation-action increment' (TMSH) or 'Apply Access Policy' (GUI), and no service interruption occurs.
