             Summary: Core dump in state_raw_http_server_open
                 Key: TS-2704
                 URL: https://issues.apache.org/jira/browse/TS-2704
             Project: Traffic Server
          Issue Type: Bug
          Components: Core
            Reporter: Sudheer Vinukonda


During production roll out of one of our properties, we observed ATS crashing with the below backtrace. Upon some investigation, we found that EVENT_INTERVAL was somehow unexpectedly being delivered to state_raw_http_server_open and is falling into the default handler resulting in a crash. While we are continuing to understand how the unexpected EVENT_INTERVAL ended up in state_raw_http_server, this protection fix was added to ignore the unexpected event.
