Re: Occasional "not recognized as a supported file format" errors when reading from S3

Here is some more insight on the issue. Remember, we are seeing this when reading small chunks from a cloud-optimized GeoTIFF on S3 with our Terracotta tile server.

On our latest encounters of the issue, we are getting it consistently on the same map tile but not on adjacent tiles that are reading the exact same GeoTIFF.
So this challenges the assumption that this is a race condition, does it not?

Btw, we also tried the solution from https://github.com/OSGeo/gdal/issues/1244#issuecomment-487164897 (CPL_VSIL_CURL_NON_CACHED="/vsis3/") to no avail.
