NServiceBus DBMS connection timeout
===

I use Nservicebus with Oracle Queues OAQ instaed of MSMQ. 
I have a problem working with a dbms server that is shutdown every day at the same time. 
In particular when my nservicebus host can't get the dbms connection it starts logging on. 
When the dbms is restarted my host restart or not randomly! However restarting my host everything is ok!

Another detail is that when my nservicebus host can't restart it logs a 'connection timeout message' every 15 seconds!

What's the behavior of NserviceBus when it's reading from a queue and the dbms crash? What could i do to solve this problem?

thank you,
