azureblob spams ListBlobs requests (> 33k rpm) when used as a blob store for tiling on geoserver 2.21.0

Thank you all for the excellent tool of geowebcache and it's integration with Geoserver!

I have been encountering unusual behaviour with the GeoWebCache azureblob plugin when used with geoserver 2.21.0., I'm hoping someone can give some pointers for debugging or provide a solution.

We are using geoserver 2.21.0, deployed in a container using this image: kartoza/geoserver:2.21.0

We have configured a number of base maps to be tiled and use the azureblob plugin to store the tiles in an azure blob store.

After tiling a digital elevation model ( from a geotiff file), our azure blob store reported very large numbers of requests to the "ListBlob" endpoint. Approx 33k requests per minute. After disabling the blob stores and restarting geoserver the requests disappeared. Re-enabling the store brought back the requests.

I have attempted to reproduce the issue on a fresh container image but have not been able to see the same behaviour.

If anyone can provide pointers on next debugging steps or potential solutions I would greatly appreciated it.

Thanks,

Brian

@bmaguireibm did you manage to isolate the issue, or found which action caused the problem?
