title: BizTalk connectivity issue to SQL during VM snapshot
body: <p>We have one VM for BizTalk and a separate VM for the SQL backend. We are using Veeam for backups which basically kicks off a snapshot of the VM. When this snapshot is being finalized on the SQL VM, BizTalk services on the application server fail. Usually they restart automatically but sometimes this requires manual intervention to start the services. The error below is logged on the BizTalk server.</p>
  
  <p>Is there any timeout setting or config changes that will allow BizTalk services to stay up during the snapshot process?</p>
  
  <p>An error occurred that requires the BizTalk service to terminate. The most common causes are the following:
   1) An unexpected out of memory error.
   OR
   2) An inability to connect or a loss of connectivity to one of the BizTalk databases. 
   The service will shutdown and auto-restart in 1 minute. If the problematic database remains unavailable, this cycle will repeat.</p>
  
  <p>Error message: [DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
