NotesDXLImporter bug or restriction importing large view?

We use views containing about 120 columns (in fact, it represents a quarter with one column for each day, + columns for week and so on)

It works for years without problem.

As we need a separate view for each quarter of each year, we launch a lotusscript agent which creates these 4 views for the year.

This year, I get an error :

<?xml version='1.0'?>

Elément de format de tableau incorrect.

DXL importer operation failed

I try to export and re-import an old view : same bug.

I try to suppress columns last columns : it works till 112 columns.

Then, if I replace the last columns by those I leave before, it works.

With more columns, even very simple ones, I get the error.

It really seems to be a problem of number of columns.

This is the first year we are in 8.5.1 : is this a bug of this version ?

Is there a limit for number of columns in DXL (documentation says 289 columns for a view wich is far away from my views) ?

Or is this a problem of length of text ? (the input file is about 76,000 bytes long)

Thanks for help
