Most likely nothing to be too concerned about. Take a peek at on Metalink/MOS:
Fatal NI Connect Error 12170, 'TNS-12535: TNS:operation timed out' Reported in 11g Alert Log (Doc ID 1286376.1)

Subject: Fatal NI connect error 12170 in alert of Oracle 11gR2 database
Hello,
Right after I upgraded my databases from Oracle 10.2.0.4 to Oracle 11.2.0.3 I am seeing the following messages in the alert log repeatedly. I didn’t see these messages in 10g databases. I tried tracking down the IP address but found out that these were computers, which had been accessing the database for many years. But these messages are being logged into the alter log only after the upgrade to 11.2.0.3.
Is it a known behavior in Oracle 11gR2? I did some checking with documentation but couldn’t find any explanation. So any help will be appreciated.
Thanks,
Ashoke Mandal
