problem with large file adding records

This file may not be large to some, but about 280000 records is the 
largest for this client.
We can not add record.  There is no error. If you try to add record via 
a processing table, it just exits.
This is my df on this box
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/md1              75671728  46409008  25418776  65% /
/dev/md0                132134     19247    106065  16% /boot
none                    515484         0    515484   0% /dev/shm

If you try adding records via 3- Add Records, it just exits.

I have tried using expanding records with a zero entry, thinking this 
might reset something in the file. No change.
When I looked at the number of records that could be added using A - Add 
Records, it says 0!

I have try to reruild a index and I get a "BixCreate failed".

I can add recods to smaller files using the 3 - add records at dclerk. 
But even on the small files A - Add Records reports 0 records can be added.

Can anyone tell me what could be happening here.

Any suggestions are welcome,
