In rarely occurring circumstances, apmd log messages might stop being sent to all logging destinations intermittently.


You cannot see any session-related apmd log messages, from any destinations including local syslog, local-db, remote syslog.


The specific conditions required for this issue to happen are unknown. Possible conditions include various configuration changes to apmd or a large number of concurrent sessions.


-- Reconfigure APM logging, e.g., change the association of log setting and access profile, and then change it back. -- As a final resort, restart apmd.
