Hi everybody,

I was taking a look at the logs and I found these warnings.

Does anybody know what is going on?

Thanks,

It looks like the connection string of the NHibernate persistence is incorrect, so it's not able to connect to the underlying server.

Check your connection string.

If it is intermittent then it is unlikely to be an incorrect connection string 

Based on the "intermittent" assumption, and your error log, I did some searching around and found this http://stackoverflow.com/a/15488923/53158 

Could you have a look and see if your symptoms and existing configuration match the description there?
