Also tested with locally built images from the kartoza/docker-geoserver repo (https://github.com/kartoza/docker-geoserver) to identify version where issue begins. Using 2.15.0 branch (Commit: 70d5bc8) build with geoserver versions:

Some fraction of WMS requests (proportion varies but generally ~15%) to this layer return images with rectangular sections missing. See attached example ‘NSIDC-g02135_extent_raster_daily_n.png’. Missing section varies.

Steps to reproduce:

  1. Create geotiff store with ‘20100101_N_20100101_extent_v3.0.tif’ and publish with attached style
  2. Make the following request repeatedly until issue manifests (reliably happens within a few dozen requests)

/geoserver/NSIDC/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=NSIDC%3Ag02135_extent_raster_daily_n&SRS=EPSG%3A3411&BBOX=-5739243.027888446%2C-8150000%2C5639243.027888446%2C8650000&TILED=false&format=image%2Fpng&TIME=2010-01-01&STYLES=NSIDC%3Ag02135_extent_raster_basemap&CRS=EPSG%3A3411&FORMAT_OPTIONS=dpi%3A180&WIDTH=1020&HEIGHT=1506
