Taking a bit of a guess at the error message format but hopefully this is close enough for the OP to modify to their liking:

Code:
awk '
$2 in V && V[$2] != $3 {
    print "Line " NR " " $3 " <> " V[$2]
    next }
{ V[$2] = $3 }' inputfile

Output for testing data:
Code:
Line 5 4321 <> 4564
Line 9 3243 <> 7654

f you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.

Edit:

or another similar solution:

Code:
awk '
{ 
  if (V[$2] && V[$2] != $3 )
    print "Line " NR " " $3 " <> " V[$2]
  else V[$2] = $3
}' inputfile
