Error description
If a message flow thread processing a message received through an HTTP Input node is terminated without sending an HTTP reply from the same thread, and the message being processed this way times out, the HTTP Input node may fail to correctly recall the HTTP message stored earlier for use during the timeout, potentially leading to unexplained CPU activity inhibiting shutdown and correct timeout processing.
