ArcGIS Server log warnings and severe warnings?

[Anonymous User]

Hello all!

We are constantly getting warning logs and severe level warnings in our ArcGIS Server Manager View Log Messages page. How in the world do I figure out what these mean? Every time I get one I google search and I get nothing that helps. Do I have to call Esri Tech support for every one of these?

Any advice would be appreciated.

Just a handful of the many for a sample:

Error: The item was not found. on a MapServer

Error processing request java.lang.NullPointerException. on Rest.

Unable to perform query operation. on a MapServer.

Error: Operation without query criteria is not allowed. on a MapServer.

Unable to process request: Error handling schema request: java.lang.Exception: java.io.IOException: Server object extension 'validationserver' not found.

Thank you!

It appears you have a SOE on the map service which is looking for additional details which map service map not have. Take a look at your SOE

Regardless of the reason for this specific log result, I'm with you. I would also like an easier way to understand what all the log results mean. I do occasionally get results from google searching etc, but it feels like ESRI could put together a more user-friendly repository of the different kinds of log results.

@Anonymous User Did you find a solution to your log warning 'object extension 'validationserver' not found' ? In my case the error appears for a branch versioned service. There is no SOE enabled on the server.

Hi there,

No, I never did find a solution. We don't use branch versioning either.

We also see this error in our logs and we don't use branch versioning for any of our data. Looking at the logs it seems to be a constant cycle of:

* Unable to process request. Error handling schema request: java.lang.Exception: java.io.IOException: Server object extension 'versionmanagementserver' not found.

* Instance of service 'System/DynamicMappingHost.MapServer' failed to process a request.

* Service instance activation failed in 'System/DynamicMappingHost.MapServer'. AutomationException: 0x80004005 - Unspecified error

* Instance of service 'System/DynamicMappingHost.MapServer' failed to process a request.

I wonder if there is a minimum ArcGIS Enterprise version to host a branch versioned feature service.  I noticed that the documentation on ArcGIS Pro cuts off at version 3.0: https://pro.arcgis.com/en/pro-app/latest/help/data/geodatabases/overview/branch-version-scenarios.ht... 

I believe ArcGIS Pro 3.0 corresponds to ArcGIS server 11.0.  We are on 10.9.1 and see the same error messages.
