XALLOC in program LIBHTTP/HTTPAPIR4

["Kim Gibson" <kgibson@xxxxxxxxxxxxxxxxxx>]

I'm using HTTPAPI to send a request to a web service and then parse the response. When receiving the response, I create a new stream file in the IFS and write the embedded XML document received in the response to the stream file. 

To create the stream file, I'm using this code:

fd = open( embfile                           
  : O_CREAT + O_WRONLY + O_EXCL +            
    O_CCSID + O_TEXTDATA + O_TEXT_CREAT      
  : S_IRUSR + S_IWUSR + S_IROTH              
  : 819                                      
  : 0 );                                     
callp write(fd: retval.valptr: retval.len);  
callp close(fd);                             

It's been working very well, until I received an error message:

  From module . . . . . . . . :   QRNXMSG                                           
  From procedure  . . . . . . :   SignalException                                   
  Statement . . . . . . . . . :   21                                                
  To module . . . . . . . . . :   HTTPUTILR4                                        
  To procedure  . . . . . . . :   XALLOC                                            
  Statement . . . . . . . . . :   3433                                              
  Message . . . . :   The length requested for storage allocation is out of         
    range.                                                                          
  Cause . . . . . :   RPG procedure XALLOC in program LIBHTTP/HTTPAPIR4 tried to    
    allocate storage with a length that was not a value between 1 and 16776704.     
    Recovery  . . . :   Contact the person responsible for program maintenance      

The HTTP header of the response in this case follows:

HTTP/1.1 200 OK
Cache-Control: private, max-age=0
Content-Length: 9767093
Content-Type: text/xml; charset=utf-8
svr: renwws02
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Date: Mon, 07 Feb 2011 19:52:11 GMT

I dumped the program, but am not sure how to tell how much memory XALLOC tried to allocate.  I do know that this response is significantly larger than most that I receive, but probably not as large as some that are going to come down the pike. 

Any ideas on where to start?

Thanks so much,

Kim Gibson
