| ERROR | TNS: listener has not received clients request in time allowed |
| CAUSE | The listener disconnected the client because the client failed to provide the necessary connect information within the allowed time interval. This may be a result of network or system delays; or this may indicate that a malicious client is trying to cause a Denial of Service attack on the listener. |
| ACTION | If the error occurred because of a slow network or system, reconfigure INBOUND_CONNECT_TIMEOUT to a larger value. If a malicious client is suspected, use the address in listener.log to identify the source and restrict access. Turn on tracing for more information. |
