sanity check failure

[scooter6 at gmail.com]

We have a process that runs at night that copies records to their permanent
file.
We input new records into a 'temp' file and this process copies them over
to the 'main' file at night and has been for years.....
I noticed a few mornings ago this wasn't happening so I ran the process
manually this morning....here is what I get:

Sanity check failure!

mvbytes < 0

File=bixins.c,  line=405

tptr = tptr=(1,0,6230,1,0)
file='mainfile' index=T

It appears it 'copies' the first record it encounters to the 'main' file
then this happens
Any clue what bixins.c  is??  It's not anything my processing is
calling.....
