Symptoms

apmd may crash when HTTP Auth agent is used in an Access Policy.

Impact

apmd daemon crash. APM cannot process requests until apmd starts up again.

This might occur on heavy load, when AAA HTTP Server is configured in 'Form based' or 'Custom body' mode. The probability of occurrence is greater if there are session variables specified in the AAA HTTP Server configuration.

Workaround

Use basic auth, or do not use HTTP Auth.
