Packet loss after configuring Ethernet Bonding

I was trying to implement Ethernet bonding for our servers . Both the Ethernet interface in my server are connected to two different network switches .

The issue for me is that I am seeing packet loss after configuring bonding . Sometimes the packet loss is around 90% .

My /proc/net/bonding/bond0 looks like this

[root@ ~]# cat /proc/net/bonding/bond0

Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009)

Bonding Mode: adaptive load balancing Primary Slave: None Currently Active Slave: eth0 MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0

Slave Interface: eth0 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: e4:e1:5b:d0:11:10 Slave queue ID: 0

Slave Interface: eth1 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: e4:e1:5b:d0:11:14 Slave queue ID: 0

[root@portaldb1 ~]# cat /sys/class/net/bond0/bonding/mode balance-alb 6
cat /sys/class/net/bond0/bonding/miimon


OS I tried are RHEL 6.2 and CentOS 5.5 , seeing the packet drops in both OS

What I am missing in the configuration ? I tried connecting both the interface to the same switch , but still seeing the packets drops . Any help/suggestions to resolve the issue will be hughly appreciated .
