> I did some googling and found that these can occur while using
> failover(either by failover API or failover broker). But we are not using any
> failover in the setup where these exceptions are occuring. I am not able to
> reproduce them either. They occur during the day randomly.
> Any ideas on why they are being logged?
> Thanks,
