Threshold issue when Performing operation on 5000+ Items in a library

Hi,
We are performing operation on  list having 5000+ items.  i
I find that any CSOM operation on the List having 5000+ throws the threshold error .
I have this code mentioned below

Whenever I try to load  below  statements for a list having 5001 docs it is throwing threshold error.

Is this a limitation using CSOM ?  

How to over come this issue ?

Error: "The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator"

cContext.Load(list2.RootFolder.Folders);

Sample code:

 string fileUrl = "https://***.sharepoint.com/sites/***";

                Uri fileUri = new Uri(fileUrl);

                var x = fileUri.Scheme + Uri.SchemeDelimiter + fileUri.Host;

                ClientContext rootContext = new ClientContext(fileUri.Scheme + Uri.SchemeDelimiter + fileUri.Host);

                rootContext.Credentials = BuildCreds();

                Uri webUrl = Web.WebUrlFromPageUrlDirect(rootContext, fileUri);

                ClientContext cContext = new ClientContext(webUrl.ToString());

                cContext.Credentials = BuildCreds();

                cContext.Load(cContext.Web);               

                cContext.ExecuteQuery();

                ListCollection siteLists = cContext.Web.Lists;

                cContext.Load(siteLists);

                cContext.ExecuteQuery();

                foreach (List list2 in siteLists)

                {

                    try

                    {

                        cContext.Load(list2);

                        cContext.Load(list2.RootFolder);

                        cContext.Load(list2.RootFolder.Folders);

                        cContext.ExecuteQuery();

                    }

                    catch

                    {

                    }

                }
