vThe heap storage allocated using malloc is not being freed. Over time, a memory
leak error like this could use significant amounts of memory. This is a common
application error that only surfaces when the application is not running in a
*NEW activation group.

/*************************************************************************/

/*******************************************************************/
numBytes = atoi(contentLength);
stdinBuffer = (char*)malloc(numBytes+1);

memset(stdinBuffer, 0x00, numBytes+1);

} else

return;
}
The following example shows the changes that would be required to this
application to allow it to run in a user-named or *CALLER activation group:
