Hi Jon - I have seen in my ArcGIS Monitor for Enterprise Portal at 10.7 the same error:
'Database found to be stopped restarting it' - and yes it does not appear to be a real error but does fill. While you are at it, could you guys look into these errors that are now appearing in the 1000s:
86 06/07/2019 11:55 AM 06/07/2019 11:46 AM 9000 SEVERE 1 Machine1.BCC.SCGOV.LOCAL 0 : ERROR: operator does not exist: character varying = integer Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts. Position: 447
87 06/07/2019 11:55 AM 06/07/2019 11:46 AM 9000 SEVERE 1 Machine1.BCC.SCGOV.LOCAL Database error has occurred.
and filling page after page of logs. For us, this framework 9000 error began about May 15 and I simply cannot track it down. I do know it's related to PostgreSql db's because of the 'character varying' portion of the error, and of course the fact that the errors are coming from my hosted site....
Here's another one:
12 06/06/2019 11:03 PM 06/06/2019 11:02 PM 9000 SEVERE 1 Machine2.BCC.SCGOV.LOCAL The submitted field 'lasteditor_count' is not available in the layer '0' of the service 'PlatBoundary'.
This last one also occurs by the 1000s but appears to be from OpenData whenever someone attempts to display the chart from the attribute as displayed in the Table tab of the open data site. I have a specific GeoNet post on this here:
Open Data Mapping and Charting Attributes throws ArcGIS Hosted Site Error
None of these appear to be impacting app performance anywhere because no one has complained but it sure would be nice to track these down and apply a fix....
Thanks,
David
