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 server.Action: If the error occurred because of a slow network or system, reconfigure one or all of the parameters SQLNET.INBOUND_CONNECT_TIMEOUT, SQLNET.SEND_TIMEOUT, SQLNET.RECV_TIMEOUT in sqlnet.ora to larger values. If a malicious client is suspected, use the address in sqlnet.log to identify the source and restrict access.

to Oracle 11.2.0.3 I am seeing the following messages in the alert log repeatedly. I didnât see these messages in 10g databases. I tried tracking down the IP address but found out that http://oracle-l.freelists.narkive.com/MhYvZ6TK/fatal-ni-connect-error-12170-in-alert-of-oracle-11gr2-database these were computers, which had been accessing the database for many years.
