NetBSD tar and large files.

[Sad Clouds <cryintothebluesky%googlemail.com@localhost>]

Any reason why NetBSD tar utility cannot create large files. I was
trying to archive about 4GB of data when I got this: 

tar: End of archive volume 1 reached
tar: ustar vol 1, 1695 files, 0 bytes read, 0 bytes written in 1946
secs (0 bytes/sec)

I can fall back on GNU tar, but it's frustrating having to wait for 30
minutes to archive data, just to find out tar "breaks" on large files.
