TMM crash when processing unexpected HTTP response in WAM
Traffic disrupted while tmm restarts.
Three conditions: WAM enabled virtual server WAM disabled during request phase WAM enabled during response phase
Do not disable WAM during request processing unless it will also be disabled during response processing. If WAM is disabled, close the connection after the response with HTTP::Close to ensure it cannot be used for future requests.
TMM no longer crashes when processing unexpected HTTP response in WAM.
