[IDS Win]How to flush Indesign server.

Question

Hi All,
I am using Indesign server to create documents which contains text, images & tables. My job is to create & export documents to pdf. Document are sometimes contains 300 plus pages. And cs2 server process this jobs one after the other in queue ..may be 100 jobs in a queue. Here after certain amount of time a 'out of memory' error comes up and Indesign server gets crashed(its around after processing 30-40 jobs).
I have taken care to delete all allocated meomary in my program through New- delete pair. Still after each job allocated memory to Indesign keeps increasing.
Is there any way so that I can purge memory from Indesign after my job complition? I tried to use 'PurgeMemory' over IDocumentList but its not that effective.
Any suggestions are most welcommed!
Thanks,
Rahul.

Well, it's been two years since the last activity in this thread, and I am having this exact same problem with InDesign Server CS4.
I have a .NET web application that calls the IDS through SOAP and simply tells it to run a JavaScript.  In simple terms, the script opens an InDesign file, imports some XML, makes some minor formatting changes, and exports the PDF to the filesystem.  The .NET webapp then receives the status message and redirects the user directly to the finished PDF which they can then view/save/etc.
This all works perfectly, but while it's running, I see the memory usage of InDesignServer.exe spike by several MB, and then it settles back down to a still-higher-than-initial value. Eventually, the InDesignServer.exe is taking up several hundred MB and my server starts giving out-of-memory errors.
I'm not sure what I'm doing wrong. Like the original poster asked, it appears as though I should be flushing something that I am not. I've researched this "ErrorList" that was referenced, and my memory "leak" seems to be bigger than this (although I could be wrong), but I can't find anything in the language reference on how to programmatically flush this after each document. I'm not even sure if this is the culprit.
Can anybody help? Many many thanks in advance
The contents of my JavaScript is as follows (and you'll see that I'm closing the document each time):
// We encapsulate the meat of the code in a main() function and then call main() at
// the bottom of the script in order to facilitate proper returns
// see http://ericwillis.wordpress.com/2008/04/18/return-value-from-indesign-server-script-via-so ap/
function main()
     // Our script requires a school code to be passed in as an argument
     // We begin by assuming that it hasn't been passed
     var message='Error: schoolCode parameter required';
     // if the argument HAS been passed...
     if(app.scriptArgs.isDefined('schoolCode'))
          // We change our return message and proceed with processing
           message='Success: No problems reported';
          // This is our work folder
          var projectPath='/E/mywebsite/';
          // this is our starting template
          var doc = app.open(File(projectPath + 'source/Template.indd'));
          // the template has been "tagged" with XML placeholders, so here we are
          // importing the data to replace them. The filename of the XML is
          // dependent on the school code that was passed as an argument
          doc.importXML(File(projectPath + 'work/' + app.scriptArgs.getValue('schoolCode') + '.xml'));
          // The next portion of the script scans the entire document for overset
          // text (text that flows outside of it's container). If any is found, it changes
          // the text colour to red so that the author knows that they overtyped
          //Create a color.
          try{
               doc.colors.item("Red").name;
          catch (myError)
               doc.colors.add({name:"Red", model:ColorModel.process, colorValue:[20, 100, 80, 10]});
          // loop through each "story"
          for(x=0;x<=doc.stories.length-1;x++)
               // if the current story has overset text...
               if(doc.stories.item(x).overflows)
                    // change the text colour to our previously created colour
                    doc.stories.item(x).fillColor = doc.colors.item("Red");
                    // Change the message too so that we know on the server side
                    // that there's a problem
                    message='Warning: Contains overset text';
               // We couldn't find a way to use styles to place an outside border
               // around a variable-width & length table that we're creating
               // dynamically in the XML. To solve this, the following loop finds all
              // of the tables in the document and places a border around their
              // outside-most edges only
               // Loop through each table in this story
               for(y=0;y<=doc.stories.item(x).tables.length-1;y++)
