datafile usage for a tablespace

Oracle 11.1.0.6 on redaht 5.1 linux.

I have 4 datafiles comprising a single tablespace with a single table in the tablespace.    As data is loaded into the table, only 1 datafile is used, and then when the

64GB maximum file size is reached, I get an error message that th table cannot extend.   There are 3 more datafiles, not being used at all.  First, why are the other 3 datafiles not being filled simultaneously, and

second, why is Oracle not finding the empty space in the other data files?     Seems a lot  like a bug, I need a fix or workaround.
