Is that on a 32-bit machine?

Seems to work okay on a 64-bit system here:

$ df /mnt/udf
Filesystem           1K-blocks      Used Available Use% Mounted on
/var/tmp/udf_fs        4798938       302   4798636   1% /mnt/udf
$ ll /var/tmp/udf_fs
-rw-r--r-- 1 root root 4915200000 Mar 30 13:49 /var/tmp/udf_fs

And after creating a large file in the filesystem:

$ ll /mnt/udf/udf_file
-rw-r--r-- 1 root root 4751360000 Mar 30 14:01 /mnt/udf/udf_file
$ df /mnt/udf
Filesystem           1K-blocks      Used Available Use% Mounted on
/var/tmp/udf_fs        4798938   4640304    158634  97% /mnt/udf
