Files not found on UNIX.

Anyone have any input on this one.  I'm running Samba version 
1.9.18p10 on an HP9000 HP_UX 10.20.  An NT 4.0 server writes files to 
a UNIX directory and periodically a shell script runs to process any 
new files found.  Occasionally a file isn't found for several hours 
after it has been created, then mysteriously appears in the UNIX 
directory.  So far this hasn't been a major problem, but these are 
orders which a dealer expects to have confirmed within the hour.
