Is it possible to disable map export from a map service?

Is it possible to disable map export from a map service?

You mean, besides stopping the service? Please provide more detail on what you are trying to accomplish.

I would like the Export Map Option to not be available

The main purpose of a map service is to render images of your data, so you somewhat defeat the purpose of the map service, but you can disable it from Manager:

Note that this causes the service to return a 500 at the root endpoint of the service, (https://server.domain.com:6443/arcgis/rest/services/SampleWorldCities/MapServer), but all other endpoints are accessible. I would still reassess the need to turn it off, though.

Yeah that will not work. Basically, we use the service in an application and AGOL and someone is trying to export the data which is crashing everything. There is also a lot of ArcSoc.exe issues going on.

What do you mean by "export the data"? The Export Map operation returns an image, not the actual data to download. If this operation is taking too long or is too CPU intensive, (lots of data, complex features and symbology, etc), then you may need to cache the data. This pre-renders the images on disk so they are returned rapidly, (again, as images, so the underlying data can't be downloaded).

What do you mean by "crashing everything"? Do you physically see the SOC process crash and create a crash dump on your machine? Do you run out of CPU or RAM? If things are just getting very slow because the service is using too much CPU, then again, caching will help that. If this data changes rapidly, then that may not be an option and you'll need to look into potentially throttling access to the service through a proxy, (search rate limiting).

I don't mean "export". Just returning the Image. It is only one service causing the problem and we know this because there is a crash dump fine that indicates the one service is having an ArcSoc.exe issue. The RAM is running at about 72% but is going to be increased to see if that helps the issue.

I'd set the logs to DEBUG and then see what's happening right before the crash, (for example, data access, symbolizing, etc). You can also upload the crash dump here so I can try to take a look or contact Support and have them troubleshoot with you. I don't think turning off Export Map is the solution as that will cause issues in any application expecting to get images from the service. Ideally, you'd identify what's causing the service to crash.

How many layers do you have in your mapservice? Do you have scale dependencies set on layers so not too many features need to be rendered?

The RAM was increased and it seems to be working for now. Below is the last error message from the dump file two days ago.

hopefully this topic can be revisited.

I have a cached/tiled map service that runs great but for some reason, if a client uses it for its "export" operation and not simply as a map service to draw up the tiles in a web map, it can get bogged down and start crashing. For example, I currently have about 6 "active requests" that are going on a few minutes from internet clients waiting for the service "export" image.

I'd love to disable clients from using that export operation and just allow the map service to serve up the tiles. I'm not sure why some clients even request "export" images vs the actual tiles.

Here's a couple examples:

Here's how I want the service to be used... simply serving up the tiles: ArcGIS API for Javascript&colon; Imagery/imagery2021FullCounty (larimer.org)

Here's what is bogged ArcGIS Server down and overloading the service (the following image is just an example of the "export" operation... I'm seeing that users are using it to get images that are very large and very high DPI and even different spatial references and rotated): export (400×400) (larimer.org)
