Why I got this error Not enough memory resources are available to process this command?

Question

In my website using ASP.NET MVC + webforms C# and crystal reports ,

When I click button to print the report using crystal report I got this error

" Not enough memory resources are available to process this command"

every 2 days I got this error I solved it by republish the site again , but I need permanent solution

This is the Code used in webform :

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                
                TXTORDERID.Text = Request.QueryString["order_number"].ToString();
                TXTDEPTID.Text = Request.QueryString["deptid"].ToString();
                TXTTESTID.Text = Request.QueryString["testid"].ToString();
                TXTCULTURE.Text = Request.QueryString["Culture"].ToString();
                
                ParameterFields paramFields = new ParameterFields();
                ParameterField paramField = new ParameterField();
                ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue();
                ParameterDiscreteValue paramDiscreteValue1 = new ParameterDiscreteValue();
                ParameterField parameterField1 = new ParameterField();
                ParameterDiscreteValue parameterDiscreteValue1 = new ParameterDiscreteValue();
                ParameterFields parameterFields = new ParameterFields();


                if (Convert.ToInt32(TXTDEPTID.Text) == 7 && Convert.ToInt32(TXTCULTURE.Text) == 1)
                {
                    TXTPOSITIVE.Text = Request.QueryString["Positive"].ToString();
                }
                if (Session["UserCustid"] != null && Convert.ToInt32(Session["UserCustid"]) > 0)
                {
    if (Convert.ToInt32(TXTDEPTID.Text) == 1 || Convert.ToInt32(TXTDEPTID.Text) == 2 || Convert.ToInt32(TXTDEPTID.Text) == 3 || Convert.ToInt32(TXTDEPTID.Text) == 4)

this is the error page :

I need your kind help please and solve this error and stop receive error on server ?

I tried to close and dispose the report document but when run the report always got error : object reference not set to an instance an object error

where I will put the code of close and dispose and not get this error

object reference not set to an instance an object error?

reportDocument.Close(); 
reportDocument.Dispose(); 

I checked this link and changed the value of Printjoblimit to 1500 in server registry is it correct?

Answer 1

Add this void after Page Load void hope this will solve the error :

protected void Page_Unload(object sender, EventArgs e)
 {
     if (reportDocument != null)
      {
              reportDocument.Close(); 
              reportDocument.Dispose();  
              reportDocument = null;
       }
 }

also about print job limit parameter in registry try to increase the value to 9000 for example and check this is the path :

“HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Report Application Server\InprocServer”
