On one server I have ArcSDE running in SQL Server 2012 (SP2), and another server I have ArcGIS 10.3.1 Server hosting a feature service that access the ArcSDE database. The feature service runs fine until I see the following error message in the ArcGIS Server log:
Error: Failure to access the DBMS server [08S01:[Microsoft][SQL Server Native Client 11.0]TCP Provider: An existing connection was forcibly closed by the remote host.
And then the following error message on every feature service request:
Error: Failure to access the DBMS server [[Microsoft][SQL Server Native Client 11.0]Communication link failure]
It seems database connection was temporary disconnected, and the only solution is to restart the service manually.
My question is: Why wouldn't the Feature Service reconnect with ArcSDE? Is there anyway around this beside restart the service manually?
