Violation is missing/details not populated in the event log page, when a POST request with large number of parameters are sent to the BIG IP system.


You cannot see the violation details.


-- A large POST request with lots of parameters is sent to BIG-IP system. -- 'Learn New Parameters' is enabled.


Disabling parameter learning helps. Note: This happens only with a large number of parameters. Usually it works as expected.
