Hi, I saw this post on the lvs-users list archive. http://lists.graemef.net/pipermail/lvs-users/2009-December/022765.html
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: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c 01843037&dimid=1001315106&dicid=alr_aug09&jumpid=em_alerts/us/aug09/all/ xbu/emailsubid/mrm/mcc/loc/rbu_category/alerts 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.
