Alex, HDF5 doesn't support attributes bigger than 64K. Dense storage was introduced to handle large numbers of attributes, but not a bigger size.
Are you saying that you cannot create an attribute bigger than 16KB (and less than 64K)? If so, an example program that demonstrates the issue will be highly appreciated. Thank you!
