Problem with BLOB s

[Johnson, Harold A EDUC:EX]

Hi all.   We have an older process that has been working well for the past
few years, which loads PDF files into our RDB database into a BLOB using the
"do blob" command (quick).  It suddenly stopped working in the last week and
will not load the files.  
The process compiles fine; it runs fine (does the command) with NO errors,
but the file is simply not stored, even after the put/commit???   (I've run
it in the debugger to check)
Any ideas what's happenning?  To further complicate this, the process has
not been changed for two years and OTHER "do blobs" into other tables are
working fine!

thnx
