No, the directory count is well below 64k. It seems to have to do with the 2Gb limit, as I always get the error for the first frame going over it. I'll try to check how the software producing those tiff writes them, it's probably the

> source of the problem: so far I haven't found a single tiff reading library able to open them completely. 

In addition to whatever software you are using to drive libtiff, it is possible that Ubuntu-provided libtiff includes patches/changes (usually due to security concerns) which causes it to differ from the original libtiff release.

I was easily able to write TIFF files larger than 2GB, and BigTIFF files of 24GB under Ubuntu using GraphicsMagick, but I am using latest

CVS libtiff and not the library provided by Ubuntu. It is also not clear if the libtiff function calls are similar to your situation.
