Oracle Server Process establishes connection to Port 1506 (utcd) on Linux

Hi,
We have one of our Production Oracle Database 11gR2 on RHEL 6 and its Live since May 2013. Recently we have noticed that some Oracle Processes are establishing connection to port 1506 (utcd). This was pointed out by the Linux Admin.

Please see the command outputs:

# netstat -pentao | grep 1506

tcp 0 0 10.60.4.5:1506 10.60.4.5:55203 ESTABLISHED 0 15453 363/oraclePROD keepalive (6198.28/0/0)
tcp 0 0 10.60.4.5:55203 10.60.4.5:1506 ESTABLISHED 0 15462 363/oraclePROD keepalive (6198.26/0/0)

363 is the Unix PID and it keeps changing.

Can anyone let me know if  this is normal or caused due to the application? I have checked this is other sites and don't find such a thing happening.

Regards,
Thiru
