    Issues after upgrade to NCM 7.4 & Latest Hotfix


      This is probably coincidence and unrelated, but we have noticed after upgrading to NCM 7.4 and applying the latest hotfix for NPM, we are now having problems with the polling engine stopping randomly and also with the alerting engine service not working properly due to intermittent database connections. This has happened 4 times since the upgrade (2 weeks ago) and we have not had any problems like this in the past. I'm not saying these problems are caused by Orion, just looking for some info. Here is what the logs look like.


      First Event


      Service was unable to open new database connection when requested.


      SqlException: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.)


      Connection string - Data Source=XXXXXXXX ;Initial Catalog=SolarWindsOrion;Persist Security Info=False;User ID=XXXXXX ;Password=*******;Connect Timeout=20;Load Balance Timeout=120;Packet Size=4096;Application Name=SolarWinds.BusinessLayerHost@domain-SolarWinds.UDT.BusinessLayer.dll;Workstation ID=SolarWinds


      Second Event

      SolarWinds.Orion.Core.BusinessLayer - Unhandled exception: Exception of type 'System.OutOfMemoryException' was thrown.


      This is followed by all Orion services dumping and restarting


      Starting Core Service [XXXXXXX]


      We are also now seeing messages about the alerting engine such as:
