Setting the switch MTU size to a higher value might help. Per http://www.intel.com/support/network/sb/CS-025841.htm, "When configuring Jumbo Frames on a switch, set the frame size four bytes higher for CRC, plus four bytes if using VLANs or QoS packet tagging." So, I would try setting the MTU size on the switch to 9018 or 9022.
I hope this helps.
Thanks Mark, set jumbo frames to 9018 and working fine now.
