I saw this post on the lvs-users list archive.

We just experienced the same thing migrating our load balancers to new
hardware yesterday.

It turned out to be a problem related to NIC hardware/drivers.

For us the problem is solved by turning of a NIC feature called
Transparent Packet Aggregation.
You do that by adding the following line to the modprobe.conf file:
options bnx2x disable_tpa=1

As proposed in:

We have HP BladeSystem c-Class c7000 with BL460c G6 and Broadcom
Corporation NetXtreme II BCM57711E 10-Gigabit PCIe NICs.

On that we are running RHEL 5.4 with Kernel 2.6.18-164.6.1.el5.

Just wanted you to know if you where still wondering since I never saw
an satisfying end of the thread.

Cheers, and have a nice weekend.

Best regards
