System out of memory exception with kentico custom repeater

Question

I am facing a very complicated situation with kentico repeater transformation, where I have created 3 custom repeaters to process the following attachments fields "Images, Reports and Files", which i created in the page type to separate attachments by type. so to process my data I followed this post to create the below transformation:

    <%@ Register Src="~/CMSModules/Content/Controls/Attachments/DocumentAttachments/DocumentAttachments.ascx" TagName="DocumentAttachments" TagPrefix="cms" %><%@ Register Src="~/CMSModules/Content/Controls/Attachments/DocumentAttachments/DocumentAttachmentsVideo.ascx" TagName="DocumentAttachmentsVideo" TagPrefix="cms" %>


< script runat="server">
   protected override void OnInit(EventArgs e)
{
    CMS.DataEngine.DataClassInfo dci = CMS.DataEngine.DataClassInfoProvider.GetDataClassInfo(Eval("ClassName").ToString(), true);

    if (dci != null)
    {
       CMS.FormEngine.FormInfo fi = new CMS.FormEngine.FormInfo(dci.ClassFormDefinition);
        // field name we added in the page type
    CMS.FormEngine.FormFieldInfo ffi = fi.GetFormField("Images");
    CMS.FormEngine.FormFieldInfo ffiReports = fi.GetFormField("Reports");
    CMS.FormEngine.FormFieldInfo ffiFiles = fi.GetFormField("Files");

     Guid AttachmentGroupGUID = ffi.Guid;
     Guid AttachmentGroupGUIDRep = ffiReports.Guid;
     Guid AttachmentGroupGUIDFil = ffiFiles.Guid;

    ucDocAttachments.Path = Eval<string>("NodeAliasPath");
    ucDocAttachmentReports.Path = Eval<string>("NodeAliasPath");
    ucDocAttachmentFil.Path = Eval<string>("NodeAliasPath");

       ucDocAttachments.AttachmentGroupGUID = AttachmentGroupGUID;
       ucDocAttachmentReports.AttachmentGroupGUID = AttachmentGroupGUIDRep;
       ucDocAttachmentFil.AttachmentGroupGUID = AttachmentGroupGUIDFil;

     ucDocAttachments.TransformationName = "CMS.Root.Attachment";
     ucDocAttachmentReports.TransformationName = "CMS.Root.AttachmentLinks";
     ucDocAttachmentFil.TransformationName = "CMS.Root.AttachmentLinks";

     ucDocAttachments.StopProcessing = false;
    ucDocAttachmentReports.StopProcessing = false;
    ucDocAttachmentFil.StopProcessing = false;

    ucDocAttachments.ReloadData(true);
    ucDocAttachmentReports.ReloadData(true);
    ucDocAttachmentFil.ReloadData(true);
    }
}
< /script>


    <div class="innerSelectedElectionContainer col-xs-12 selected-<%# DataItemIndex %>">
    <div class="col-xs-12 selectedElectionInfo selectedContent-0">
        <div class="col-xs-12 selectedElectionTitle elem-to-hide">
            <%# Eval("Title") %>
        </div>
        <div class="col-xs-12 selectedElectionText elem-to-hide">
            <%# Eval("Text") %>
        </div>
    </div>
    <div class="selectedElectionInfo elem-to-hide selectedContent-1">
        <div class="col-xs-12 photosLabel"><%# Localize("{$photosGallery$}") %></div>
       <div class="col-xs-12 noPaddingSides FlexWrap"> <cms:DocumentAttachments ID="ucDocAttachments" runat="server" PageSize="100" GetBinary="false" />

          </div>
    </div>
    <div class="selectedElectionInfo elem-to-hide selectedContent-2 col-xs-12">
        <div class="col-xs-12 photosLabel"><%# Localize("{$videosGallery$}") %></div><cms:DocumentAttachmentsVideo ID="DocumentAttachmentsVideo" runat="server"  GetBinary="false" StopProcessing="true" ImageFieldValues='<%# Eval("Videos") %>' />
    </div>
    <div class="selectedElectionInfo elem-to-hide selectedContent-3">
              <div class="col-xs-12 photosLabel"><%# Localize("{$reports$}") %></div>
       <div class="col-xs-12 selectedContent-3 ElectionReports"><cms:DocumentAttachments ID="ucDocAttachmentReports" PageSize="100"  runat="server" GetBinary="false"  StopProcessing="true" /> </div>
    </div>
    <div class="selectedElectionInfo elem-to-hide selectedContent-4">
       <div class="col-xs-12 photosLabel"><%# Localize("{$files$}") %></div>
       <div class="col-xs-12 selectedContent-4 ElectionFiles"><cms:DocumentAttachments ID="ucDocAttachmentFil" PageSize="100" runat="server" GetBinary="false" StopProcessing="true" /> 
         </div>
    </div></div>

But the problem is that the system is now returning an out of memory exception, which was for certain time temporary, but now the website is not processing at all, i am having a hard time finding the reason, because the system works for some data, and after a certain refresh it returns the exception for the same data, so its random, here's a screenshot for the event logs:

when referring back to the code behind I found that the exception is executing on this line: ucRepeater.DataSource = ucDataSource.DataSource;

Does someone knows whats wrong and how can I fix this??

You can continue posting in your original thread here, even if it's answers:

https://devnet.kentico.com/questions/system-outofmemoryexception

If there binary didn't fix it permanently, and If you still have memory issues I would look at the database or web server if you are running out of memory in general.

Also check system > general and see how much memory is being used in the cache, if you are caching to much that may be causing your memory to reach it's limit.

Thank you trevor, well no I tried to add "GetBinary = false" and it worked for a short time then it went back to giving the same exception, after some data filling, actually I dont think this is related to the physical memory, as per this link https://stackoverflow.com/questions/1153702/system-outofmemoryexception-was-thrown-when-there-is-still-plenty-of-memory-fr , do you have another opinion? – farah el agha Jan 15 '18 at 14:05
