pg_dump large-file support > 16GB

Hello

We are having problems with pg_dump.

We are trying to dump a 30GB+ database using pg_dump with the --file
option. In the beginning everything works fine, pg_dump runs and we get
a dumpfile. But when this file becomes 16GB it disappears from the
filesystem, pg_dump continues working without giving an error until it
finnish (even when the file does not exist)(The filesystem has free
space).

I can generate without problems files bigger than 16GB with other
programs.

Some information:
---------------------------
OS: Red Hat Enterprise Linux WS release 3 (Taroon Update 4)
Kernel: 2.4.21-27.0.2.ELsmp #1 SMP i686
PG: 7.4.7

LVM version 1.0.8-2(26/05/2004)
EXT3 FS 2.4-0.9.19, 19 August 2002 on lvm(58,6), internal journal
EXT3-fs: mounted filesystem with ordered data mode.
----------------------------

Any ideas? It looks like pg_dump has a limit of 16GB? How can we solve
this?
