We are running ArcGIS Server 10.8.1 on EC2 instances in AWS, The instances run based on an AMI that was created by ESRI for AWS where ArcGIS is installed to /arcgis. We have 2 servers in an autoscale group that is behind a load balancer. The server has a number of Feature Services published to it and we have users using an in house developed iOS app that uses the esri sdk as well as people using ArcMap and ArcPro to communicate with the feature services. The iOS app uses createReplica, synchronizeReplica API calls to create local gdb's and update the source database.
We occasionally see error messages in the /arcgis/server/usr/logs/*/services/* that look like the below, and I am trying to track down why they might be occurring, any advice would be appreciated
[2025-01-30 00:08:24] <Msg time='2025-01-30T00:08:24,654' type='SEVERE' code='17000' target='V3/Roads_FireTrails.MapServer' methodName='GraphicFeatureServer::GenerateDatasetsForReplication' machine='<internal_ip_removed>' process='8296' thread='477' user='anonymous' requestId='6485f2f2-0ab2-4df6-a2ab-cc1082f90178'>Layer 10 is not part of the service.</Msg>
In the case of this error message occuring people are no longer able to perform replica related operations with the feature server and the feature server needs to be restarted before it starts working again (fortunately I have automated this) but it would be good to work out why its happening.
