Symptoms

The message "http_process_state_parse_header - Invalid action EV_BODY_COMPLETE during ST_HTTP_PARSE_HEADERS" appears in /var/log/ltm

Impact

Filters may receive an extra HUDCTL_RESPONSE_DONE or HUDCTL_REQUEST_DONE event that they do not expect. This may generate messages in the logs, or other unwanted behavior.

Conditions

If a filter decides to message the proxy while handling a request or response done event, the proxy may re-send that event again.

Workaround

None.

Fix Information

The TCP proxy no longer can accidentally resend request or response done events.
