Bonds and iSCSI failover

We are using DSS V6 6.0up14.8101.4221 64 bit (update u00626). We have created a bond over two interfaces (eth0, eth1) and defined the iSCSI failover over the bond and another interface.

When the bond has got heavy network load, one of the interfaces is disabled and enabled after three seconds, e.g.:

08:52:18|bonding: bond0: link status definitely down for interface eth0, disabling it
08:52:21|bonding: bond0: link status definitely up for interface eth0.

Is it a serious problem or a normal process when dealing with bonds and failover? When it isn't serious, is there a way to disable that notifications?

Thank for your help.
