155I have a windows service that communicates with a DB residing on a different server. The service is installed and always running. The service will look out if there any new records in the DB Table and get 1000 records at a time via stored proc and process records (updates/creates in the CRM 2016). Logic is working perfectly alright but the problem is with service going to idle state (this service shows as running in windows services but won't execute the method 'ProcessNewOtranRecords' that calls stored proc) after few hours. When the service is restarted it again works as expected for few more hours.
Please suggest me if there is any good approach to keep service active all the time.
