I was going over our Server (v10.4 on Win 2008) logs and came across the error (and stack trace) below repeatedly. It's appears to be having issues with the WMS server, but the service in question does not have WMS capabilities turned on (just MapServer). Digging around on GeoNet and GIS StackExchange I can only find similar errors related to the feature server SOE but those seem to be database access issues. The service in question draws just fine in both ArcMap and using the default JS viewer.
Any ideas on what's causing this?
Error handling request to service '<folder>/<service>.MapServer'. java.io.IOException: Server object extension 'wmsserver' not found.
