The 1024 MB filesize limit is an operating system default.... you can
allocate files up to 2 GB in size on AIX but you need to update
/etc/security/limits to either globally or on an individual user basis,
give them permission to do so.  For instance, to give root permission to
allocated 2 GB files, in /etc/security/limits.....

root:
        fsize=4194302
