Hello,
we've had an issue with our system here that seems to indicate it having trouble with a 2GB file.   It sounds like it would be the 2GB file system limit issue, except that i believe its set for unlimited.  The system indicates:

# uname -r
B.11.31

# ulimit -f
unlimited

is there something else missing here?

`ulimit` shows if there are any shell restrictions on the resources a user can consume, though there may be filesystem limits as well. Or old code may not be able to handle files larger than 2GB.

See if the user can create a large file with e.g.
`prealloc /path/to/filesystem/3GB_filename $((3*1024*1024*1024))`

Or you can check if the filesystem allows largefiles with
`mkfs_vxfs -m /dev/filesystem/specialfile`   [Get the device name from bdf or fstab]
("largefiles", i.e. files > 2GB is the default in 11i v3, but the filesystem may have been tuned for another purpose)

In what version of UX the filesystem was created? 2GB was default filesystem file size limit on UX10 32bit.
Also if you compile some daemon (ftpd) on old system, it will not handle big files.
