Umbraco version 7.10.4
Hello, it seems that after the upgrade we getting a lot of the following errors:
2018-08-03 12:38:18,658 [P3720/D2/T34] ERROR NHibernate.Util.ADOExceptionReporter - A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)

System.Data.SqlClient.SqlException (0x80131904): Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding. ---> System.ComponentModel.Win32Exception (0x80004005): The wait operation timed out
at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)
We have a loadbalance scenario, and mostly server 2 gets this exceptions.
The SQL server is reachable from this machine.
Any ideas what we could do/check?
Thx, fabian
