Hi,

I'm running a program to update the database. Program works fine on small databases like for 500 records, but when I run it on large database it abends with following description:

Code:
IEA995I SYMPTOM DUMP OUTPUT  228                           
  USER COMPLETION CODE=4083 REASON CODE=00000004

 END OF SYMPTOM DUMP                                       


In abend aid, I get the following information:

Code:
A program check was trapped by Language Environment.  During the error     
handling process, Language Environment determined that there was an error   
with the chaining of the dynamic storage areas (DSA) and issued user abend 
4083, reason code 04.  The save area is located at the beginning of the DSA.
                                                                           
A save area back chain pointer contains a value that is not a fullword     
aligned address.  Save areas must be fullword aligned.  Also, check to see 
if the back chain pointer contains the character string of "F1SA"           
(X'C6F1E2C1') which indicates use of the linkage stack.                     
                                                                           
Use of the linkage stack is not supported by Language Environment.         
                                                                           
The information pertaining to the program check is no longer available.  The
problem with the save area may be related to the original error.  Abend-AID
will print the save area chain from each end to indicate what program calls
were made.                                                                 
                                                                           
Following is the save area chain using the back pointer (BCK) starting with
the save area at 0DB45518. All addresses are resolved as 31 bit addresses.
                                                                           
Backward save area chain                                                   
                                                                           
                                                                           
Following is the save area chain using the forward pointers starting with 
the Language Environment Dummy DSA at 000FB630. All addresses are resolved
as 31 bit addresses.                                                       
                                                                           
Forward save area chain

The program DFSPCC32 was compiled on 30DEC2010.                           
It is part of load module DFSPCC30.                                       

The module was dynamically loaded.                                 
                                                                   
The module was loaded from LINKLIST library SYS1.RESLIB.           
The module was link edited on 03MAR2011 and is 00001EF8 bytes long.

I'm not able to figure out what is causing the abend.
And for that matter, How to analyze/process the above data to find out the problem.

Hello,

Suggest you ask your technical support people which debugging tool(s) might be available.

If there are none, you can put "footprints" in your code to determine where the problem occurs.

Thanks Dick..I added "footprints" in the code. Program is updating one particular segment using and Input file. And one of the record was occuring more than the defined Segment array limit in Database and causing the error.

I lurk around this topic to see what might be the solution; as you get U4083, which LE callable abend and IMS is involved, so was curious for the solution. Appreciate your efforts of telling what worked for you, Thanks.

usually when SMALL works and LARGE does not
some array/table has overflowed
