Requests to /my.policy are not getting HTTP responses. Log file '/var/log/apm' contains large number of error messages about failed XML data creation: err apmd[5076]: 01490207:3: SAML Agent XML thread specific data creation error: ERR_FAIL.
APMD will not able to process any requests.
This issue occurs when all of the following conditions are met: -- Your BIG-IP APM system is configured with a large number of access policy agents. -- You are performing an operation that requires the apmd process to start. -- For example, your BIG-IP APM system is reloaded, you install a new image, or you manually restart the apmd process.
For some configurations and platforms, you can use the following steps to recover: - Remove all unused access policies (if applicable). - Restart apmd.
Now APMD initialization will no longer fail at XML initialization when a large number of access policies/agents are present in the configuration.
