VisualAge RPG problem

Hi, all,

I recently inherited responsibility for supporting an older VisualAge RPG 
application that's used by one of our businesses.  This application is for 
entering and tracking custom orders placed by our customers.  On the main 
screen, there's a Combination box configured as a Drop-down list, which 
contains the names of people who authorize particular orders.  The application 
stores both the name and the index in the database on the iSeries, and when an 
order is pulled up for maintenance or inquiry the %setatr function is used with 
the index to set the name to be displayed in the box.

There were 9 names in the list; now there's a request to add a tenth name, 
which I've done by adding it to the list in the Data tab.  Selecting the tenth 
name at order entry isn't a problem - the record is written correctly.  
However, I'm finding that when I pull up an order for maintenance on which that 
tenth name has been selected, I get the following error:

"1408 There are insufficient resources to complete the operation.
Cause . . . . . :   The system does not have enough resources
available to complete the operation."

The other nine names work fine.  The index variable is two digits, so 
logically, that doesn't seem to be an issue.  Is there some limitation in the 
product that causes this, or is there something I need to adjust in the source 
or the settings?

I'm at Version 6.0.0, Build V6R1_20050401, Service Pack 6.0.1.

Thanks!
