Hi,

I have report - PDF page - that run sometimes on large amount of data.
with too much data, it failed when loading the page to the screen, so I try different approach- generating the page in background, and attach it to the chatter.
It does incrase the capacity of the report, but still in some amount of data it fails, and I can see in log Internal Salesforce.com Error.
I'm not hitting any other SF limitation (CPU close to limit, but not beyond).

The PDF (that failed) expected to be ~1.5MB, with ~800-1000 pages.
I able to generate it with ~1MB, ~600 pages.

Anyone have idea possible reason for this error?




global class AddPdfToRecord{
    webservice static void addPDF(){ 
     
       PageReference pdf = Page.TestLiron;
      
       pdf.getParameters().put('parm1','111');
       pdf.getParameters().put('parm2','222');
 
       pdf.setRedirect(true);
      
      //system.debug('URL: ' + pdf.getURL());

       Attachment attach = new Attachment();
       Blob body;
       try
       {
           body = pdf.getContentasPDF();        //here the failure

            // post to chatter
            FeedItem post = new FeedItem();
            post.ParentId = '0F9c00000008efE'; // nickforce chatter group id
            post.Body = 'Report for..';
            post.Type = 'ContentPost';
            post.ContentData = body;
            post.ContentFileName = 'FMR_TEST' + '.pdf';

            insert post;
       }
       catch(Exception e)
       {system.debug('EEEEEEEEEEEEEEEE'  + e) ;}
   }
}
