Re: Heap Space error MCH6902

["David Morris" <dmorris@xxxxxxxxxxxxx>]

Gary,

It would be really helpful to know what the program was doing at the time 
the error was received, the type of program, and what programs are actually 
is sending/receiving the error.   You do have control over heap storage via 
APIs or through built in language support.  I have received CEE0810 when 
trying to deallocate heap storage that was not previously allocated.  That 
was the expected result.  This sounds more like a system program receiving 
an unexpected error.  

Have you tried searching for an APAR that references this message?

Hi,

I sent this out to the RPG400-L@midrange.com list and didn't get any 
response.  I'm wondering if anyone on this list might have an idea and be 
able to give me some clue as to what to do.  

Sorry to the people that are on both lists and received this a second time.

I've never run into a heap space problem before.  I received this error
while running a program.  I'm on V4R4.

Message ID . . . . . . :   MCH6902  Severity . . . . . . . :   40          
 Message type . . . . . :   Escape                                    
Message . . . . :   The requested heap space operation is invalid.         
         
 Cause . . . . . :   The requested heap space operation is invalid. The
 heap space identifier is 0. The activation group mark is 21439. The
 activation   group mark will be zero if the heap space is not associated
 with an activation group. The error type is 2. The error type
 indicating why the heap space request is invalid are defined as
 follows:                                 

      0001-Attempt to destroy the default heap space;                      
      0002-Attempt to free or reallocate heap space storage that
      is not allocated;   The heap space identifier and activation group mark 
may not be valid for this error type;
      0003-Access to the heap space is not allowed;

It sounds like heap space is not allocated.  Does anyone know what needs 
to be done to allocate heap space.  I thought the user didn't have any 
control over heap space.  

TIA,
Gary Kuznitz
