intermittent exception from iControl.SystemFailoverBindingStub.get_failover_state

We have seen the exceptions below intermittently (maybe one out of a few hundred trial?)

It is happening intermittently from the same api, iControl.SystemFailoverBindingStub.get_failover_state. The thing I can think of is that we are not using the axis.jar that comes with iControl_11.3.jar as a bundle (but this is also 1.4). We are using just apache.axis 1.4. like the following: org.apache.axis axis 1.4

Would you please look at the following exceptions and let us know what causes these exception? As I said already, it is not always happening, just once out of a few hundreds calls. You think this is kind of concurrent issue?
