My guess ...

Yes, Solaris 10 allocates on demand, probably in response to a system call. However Oracle presumes that it has already been allocated and tries to use it - it ain't been allocated when Oracle wants it and so you have a race.

I suspect this will be an ongoing problem that tracks Oracle history: Ever notice that you need to pre-allocate the tablespace (or grow it in pre-defined chunks), even though a lot of other RDBMSs grow on demand? Oracle likes to have things presized so there are no (or minimal) delays to accomodate expansion.
