IPSEC over load-shared T1s (per packet)

Hello All Recently we doubled our internet bandwith to two T1s from the same provider that terminate on in the same router on the NOC side. We setup IP LOAD-SHARING PER-PACKET on each of the serial links on both sides (NOC and Us) in order to get an aggregate 3.0mbit. PER-PACKET routing alternates usage of the T1s, one for one... Since then, VPN performance has taken a dive. Sniffing out traffic, ESP packets are sent 3-4 times before they can be properly decrypted. Someone along the way said that using PER-PACKET routing changes the CRC value of the packets. Is this correct, has anyone else seen this issue? I can't see how the CRC is changed, the hop count isn't changing, the lines are identical, and they terminate in the same router, so the last hop is the F0/0 interface of the router before getting to the firewall.
