I am getting a ton of SEVERE errors in my server logs -
They are essentially 2 different ones: This exception was thrown after the response was committed. Access to this resource is not allowed - Code 9002 and Response already committed. Cannot forward to error page. - Code 9001.
I went looking in the logs after I was experiencing problems publishing static/pre-generated tiles. It looks like the tiles are generating on my server - I can view the "bundles" in my cache directory but they do not show up in the browser - I only see the basemap. I can click and query the tiles - so even though they aren't visible I can see a popup. If I select generate tiles dynamically it works.
I'm hoping the two issues are related.
Seems to be a known bug: BUG-000165261 for ArcGIS GIS Server
