CRS326-24G-2S+ UDP Unicast issue

I have a CRS326-24G-2S+ that is configured with several VLANs via the bridge with hardware offloading. Several VLANs are configured and working on other vlan ID’s. Several devices are able to send multicast UDP mpegts streams on vlan7 just fine. I have a pair of devices that send and recieve a Unicast UDP mpegts stream though that are not able to operate smoothly. Things work fine when I use a different unmanaged switch, but when I move them to the CRS326, I get periodic interruptions in the stream. Do you have any suggestions on how to debug this problem?
