I have actually found a fix for the issue. &nbsp;It seems that there were not enough resources (physical memory) for the database to remain up and running. &nbsp;I took down the other databases and then rebooted the box. &nbsp;Then, one by one, started the databases and everything came up. &nbsp;My assumption at this point is that there is a memory leak in one of the databases/applications that is causing the issue.
