NFX file size limit

[hendrik@topoi.pooq.com]

My program is writing trace output via printf to standard output on an 
i386 sarge system.  Standars output is redirected to an NFS-mounted 
reiser partition on an etch AMD64 machine.  It hit thr wall at 
2147483647 bytes, giving me the message

File size limit exceeded

ls tells me 

-rw-r--r--  1 hendrik hendrik 2147483647 2006-03-08 09:41 traceout

Now how do I dismantle this limit?  Is it a printf and fprintf 
limit? a stdout limit? an NFS limit?  a kernel limit on one machine or 
the other?  Or (I suspect not) a reiser limit?

And how do I get around it?  I really do still have 73G free on the 
target partition, and I'd like to get to use them.
