MCH3203 - IBM Explanation applies to V5R2??

["Peter Vidal" <Peter_Vidal@xxxxxxxx>]

Sorry, the subject was wrong (it should be V5R2)...

Thanks!

        Subject:        MCH3203 - IBM Explanation applies to V5R3


Today, we got this message in a program. 
This has been very well documented everywhere:

50   11/02/04  01:11:52.198856  QWTPITPP     QSYS        0754     *EXT 
  Message . . . . :   Job ended abnormally because of error code MCH3203. 
 
  Cause . . . . . :   The job was ended by the system because an error was 

 
    found, and the job was in a condition where the process default 
exception 
    handler (QMHPDEH) could not be given control. The system will not give 

 
    control to QMHPDEH when the job is in between the starting phase and 
the 
    problem phase, or between the problem phase and the ending phase. Some 

of 
    the more common error codes and their meanings follow: 

    MCH3203 - A machine
    function check occurred.  The most likely cause is that the program 
stack 
    for a routing step was nested too deeply.  This is probably due to 
repeated 
    calling of the programs. 

Once upon a time, IBM answered like this:

/===========================================/

"The error is due to overflow in the activation mark counter for the job
(each job has one such counter).  Within a job, each activation group,
program (re)activation and service program (re)activation uses an
activation mark which is an integer ID unique within that job.  As of V4R5
and V5R1, at the SLIC level the counter is an 8-byte integer, while at the
MI level only the 4 low-order bytes are used...

This scenario will typically appear in very large, long-running jobs,
typically server jobs or batch jobs processing large amounts of data.
Suggestions on avoiding this problem revolve around reducing usage of
activation marks to ensure the counter does not overflow:
 o   Avoid running programs in activation group *NEW unless there is a
     functional reason to do so.
 o   Avoid deactivating/reactivating programs unnecessarily (for example,
     in ILE RPG turn the LR indicator on only when it is really necessary;
     otherwise, use RETURN).
 o   Split up data processing into multiple smaller jobs, if viable.

 o   End/restart server jobs as needed."

/===========================================/

My question is:  is this answer applicable to V5R2??
