User Defined Function Problem

I have a problem that I'm not quite sure how to even begin to describe but
here goes.

Here is the statement that I am running:

SELECT A.ASCOMP AS COMPANY,
       TRIM(A.ASBECD) AS ITEM,
       '   ' AS SKU,
       CWMPINH.GETBODATE(A.ASCOMP, CAST(A.ASBECD AS CHARACTER(12)), 
                         CAST(' ' AS CHARACTER(14)))
       FROM CWMPDTA.INIOFRL1 A
       WHERE A.ASCOMP =001
       AND TRIM(A.ASCACD) IN ('6W4')

My function GETBODATE is a service program comprised of a module which
prepares some parameters and simply calls an under lying RPGLE program which
passes back a date.

My function works great the first time it is executed from Ops Nav.  It may
even work a couple more times but if the user closes their session and opens
a fresh one.  The next time the statement is executed, they get an error.

Here's the error:  SQL State: 38501
Vendor Code: -443
Message: [SQL0443] *N

The under lying joblog says basically - 


     User-defined function error on member INIOFRL1.


 


                         Additional Message Information


 


 Message ID . . . . . . :   CPF503E       Severity . . . . . . . :   30


 Message type . . . . . :   Sender copy

 Message . . . . :   User-defined function error on member INIOFRL1.


 Cause . . . . . :   An error occurred while invoking user-defined function


   GETBODATE in library CWMPINH. The error occurred while invoking the


   associated external program or service program WEB010R1 in library
CWMPINH, 

   program entry point or external name WEB010R1, specific name GETBODATE.
The 

   error occurred on member INIOFRL1 file INIOFRL1 in library CWMPDTA. The


   error code is 3. The error codes and their meanings follow:


     1 -- The external program or service program returned SQLSTATE 00000.
The 

   text message returned from the program is:  .


     2 -- The external program failed before it completed.


     3 -- The database timed out waiting for the program to return. The
timeout

   value used by the database was 0 minutes and 30 seconds.


 



I can run this a million times from green screen SQL without a problem.

Any ideas??????
