Resolution

These connections are rogue connections that have been established to the
CCI at some time and now CCI is trying to connect back. Quite often this happens if somebody does a port scan through the network.

To rectify this you can either recycle CCI or you can issue the following command to remove the connection from CCI :
 
 ccinet disconnect ::ffff:nnn.nnn.nnn.nnn
 
 Where nnn.nnn.nnn.nnn is the IP address displayed in the CAICCI_W_2014
 message.
 
 You can also do the following which will stop all connections from trying to
 be reconnected.

$CAIGLBL0000/cci/scripts/envsetlocal  (755 root sys permissions)
add the following contents:
 
 CAI_CCI_NORECON=Y
 export CAI_CCI_NORECON
 
 Recycle unicenter and cci.
