Running Geoserver 2.10.4 with a Postgres/PostGIS database.
Configured ImageMosaic extension with a Netcdf store.
I'm seeing errors when multiple requests are being processed for the same
CoverageID, and either a scalingFactor is applied or a outputCrs/subsettingCrs
is specified. Issues don't seem related to each other, but they only come up
when multiple requests are being handled concurrently.
Sample request parameters (CoverageId removed but it is the same for all
requests):
1. (Good)
geoserver/wcs?service=WCS&version=2.0.1&request=GetCoverage&subset=Lat("0","90")&subset=Long("60","150")&format=application/x-netcdf4
2. (Random scaling error):
geoserver/wcs?service=WCS&version=2.0.1&request=GetCoverage&subset=Lat("0","90")&subset=Long("60","150")&format=application/x-netcdf4&scaleFactor=0.4
3. (Random CRS error):
geoserver/wcs?service=WCS&version=2.0.1&request=GetCoverage&subset=Lat("0","90")&subset=Long("60","150")&format=application/x-netcdf4&outputCrs=http://www.opengis.net/def/crs/EPSG/0/4052
My tests involve sending 5 requests at the same time, each with a slightly
different subset on Lat/Long. For #1 above, all responses are correct.
For #2 above, sometimes 2/5 return an exceptionreport, sometimes 3/5.
For #3 above, only 1/5 request works, the other 4 return an "invalidCrs"
exception report.
Note that all requests return the expected responses only if a single request
is sent at a time.
Any help will be appreciated.
scaleFactor causes following exception on most requests:
