Dear all!
We are running a Python application an a linux distribution (RedHat)
which creates clips in MBTILES format from a WMS. We are using the
Python-API and are basically doing something like this:
src_ds = gdal.Warp(
tmp_file,
ds_in,
format='GTiff',
outputBounds=[bbox[0], bbox[2], bbox[1], bbox[3]],
dstSRS=output_srs,
)
ds_out = gdal.Translate(
out_filepath,
src_ds,
format='MBTILES',
creationOptions=creation_options,
)
The application throughs an error from time to time since a few days. We
couldn't figure out a pattern yet and therefore we are also not able to
reproduce the error. The error is the following:
Mon Nov 15 13:48:13 2021: CPLError: GDALWMS: Unable to download block
2765, 602.
URL: TCP connection reset by peer
HTTP status code: 0, error: TCP connection reset by peer.
Add the HTTP status code to <ZeroBlockHttpCodes> to ignore this error
(see http://www.gdal.org/frmt_wms.html).
Mon Nov 15 13:48:13 2021: CPLError: /wms_xml/wms_config.xml, band 1:
IReadBlock failed at X offset 2764, Y offset 601
Mon Nov 15 13:48:13 2021: CPLError: GetBlockRef failed at X block offset
2764, Y block offset 601
The exact same data gets processed successfully in one run and not
successfully in another run. We didn't change the code nor the Python or
GDAL version. Hence, we are kind of puzzled as the error comes and goes
seemingly at random.
Does anyone of you have any hints?
Thanks & best regards!
Roman
