> Any suggestions on how to troubleshoot it? 

the root cause is that you have a common MAC address appearing in two
places.

if that server you have on port 6/11 the server behind the LD?

if it isn't, I suggest you trace WHY traffic is leaking where it
shouldn't be.
OR: investigate whether two servers have the same MAC address (shouldn't
happen, but alas some NIC manufacturers have made mistakes...).


cheers,

lincoln.
