[gdal-dev] Read error on large VRT files

I sometimes get read errors when trying to convert large input VRT files
into a single BigTIFF file, typically applying an outsize of e.g. 50% or
25%. Errors are like
ERROR 1: TIFFFillTile:Read error at row 11264, col 11264; got 46 by
tes, expected 84
ERROR 1: TIFFReadEncodedTile() failed.
ERROR 1: 2352/2592_BUCNFD.tif, band 1: IReadBlock failed at X offset 45,
Y offset 47
The tile that returns the error can be converted alone without problems.
All together the number of tiles of the VRT can be towards 6000, having
100 GB in total, tiles are LZW or Deflate compressed TIFF's.
Is there a possible source of errors when trying to read and convert
VRT's of compressed TIFF of that size?
Thanks for any hint
