[SR-Users] t_relay changing source IP?

So we have a box that's bound to all interfaces on the server, and one specific IP address (that is an HA IP), and I've run into a bit of an odd behavior that I cannot explain.
For 99.9999% of our traffic, the invites come into the HA IP, and then are forwareded out the HA IP to an SBC for further processing. In a very rare instance however, I have found that there is an invite coming in the HA IP, and for some unknown reason it gets forwarded out the *interface* ip instead of the HA IP.
188.8.131.52 -- invite --> 184.108.40.206 (ha IP) -- invite --> 220.127.116.11 (sbc)
18.104.22.168 -- invite --> 22.214.171.124 (ha IP) *something happens here* 126.96.36.199 (interface IP) -- invite --> 188.8.131.52 (sbc)
I've been through tm, tmx, and the incoming invite of a working and non working request with a fine toothed comb and I cannot for the life of me explain this behavior. Any thoughts?
