What does your ml_add_table_script call look like when you create the upload_insert event? The following worked perfectly for me :
call ml_add_table_script( 'v16', 'Admin', 'upload_insert', '--{ml_ignore}');
I've attached a file (cons.txt) that shows how I create the SQL Anywhere consolidated database, and the associated MobiLink Server log file with -v+ (mlsrv16.txt) that is created when a synchronization occurs.
