C# Lotus Notes Problem AllocHandle: OUT OF PRIVATE HANDLES!

Hi,

I have an issue where I am getting the below error when interrogating a Notes database through my c# application.

AllocHandle: OUT OF PRIVATE HANDLES! -- pid 00000F38 Handles used so far 6339, Maximum Handles - 16440, error - 0x107

Maximum number of memory segments that Notes can support has been exceeded

I understand the error is due to the Domino private handles limit being reached which I believe is 6,339 although I've read that this has been increased to over 10,000 in more recent versions.  I can't do anything about the Lotus Notes infrastructure in my company so I am trying to work around this issue.

The Notes database I need to search has 10,000 dcouments but the view can't be searched on the using the field I wan't to find.  I've devised a way where I can work out the required document number I need but in the case that the value I'm looking for doesn't exist I would have to check the value of a notes item in each of the 10,000 documents.  In this situation I get the above error when I hit around the 6,000 checks mark.

The code I'm using is similar to the below,

NotesSession session = new NotesSession();
session.Initialize(password);
NotesDatabase NotesDb = session.GetDatabase("NotesServer", "aNotesDB.nsf", false); //Open Notes Database
NotesView pwdView = NotesDb.GetView("(aNotesView)");

for (int i = startingDocNo; i <= startingDocNo + 1111; i++)
{

NotesDocument ndoc = pwdView.GetNthDocument(i);
NotesItem noRef = ndoc.GetFirstItem("aNotesItem");
                            if (aReference ==noRef.Text)
                            {
                                NotesItem theValue = ndoc.GetFirstItem("valueINeed");
                                valToReturn = theValue.Text;
                                theValue = null;
                                break;
                            }

                            ndoc = null;

}

pwdView = null;
NotesDb = null;
session = null;

I have tried executing this code in chunks of 1,000 documents but I still get the error.  I thought that as I was initializing a new NotesSession object after nullifying the previous one this would reset the handle count.  I also tried spawning a new thread to process each 1,000 documents thinking if it was a new thread it could get round the limit but still no luck.

Has anyone got any ideas how to work around this problem, I'm pretty stumped!

Thanks

Richard
