Hi Jonathan
So the errors that are popping up during this time period are as shown below.
SEVERE | 29 Apr 2019 00:06:47 | Failed to construct instance of service 'ElizabethLine/CrossrailEstates.MapServer'. Service startup timeout. | ElizabethLine/CrossrailEstates.MapServer |
The server in question gets restarted (ArcGIS Server service only, not the server itself) at 23:00, I'm not sure how long the restart takes, particularly as the Windows Application Event log records the following:
The description for Event ID 5 from source ArcGIS Server cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
ArcGIS Server
The specified resource type cannot be found in the image file
Does that sound like typical behavior for ArcGIS Server?
