Content Iterator Problem

Question

Hi There,
For Solving the large list threshold error i recently added content iterator concept to my application code. 
But in my case, it is showing threshold error even after  implementing content iterator concept.
I followed all the rules as for as Content iterator is concerned. and after research in all the websites i am asking you this question.

Hi ,
Thanks for looking into this.
In Test environment, there are 6500 items in document library. And Hence Set
List View Threshold Limit to
5000 in the Web Application. When we query to document library using Content Iterator Concept, we get following error message.
"The Attempted Operation is prohibited because it exceeds List view Threshold enforced by Administrator."
Please refer below code written.
public static DataTable SearchQueryContentIterator(string strQuery, SPList somList)
SPListItemCollection itemcoll = null;
DataTable dtResults = new DataTable();
ContentIterator contentiterator = new ContentIterator();
try
SPQuery query = new SPQuery();
query.RowLimit = 2000;
query.QueryThrottleMode = SPQueryThrottleOption.Override;
query.Query = strQuery + ContentIterator.ItemEnumerationOrderByNVPField;
query.ViewAttributes = "Scope=\"RecursiveAll\"";
query.ViewFields = string.Concat(
"<FieldRef Name='ProjectNumber' />",
"<FieldRef Name='ProjectName' />",
"<FieldRef Name='SalesOrderNumber' />",
"<FieldRef Name='SMSIDNumber' />",
"<FieldRef Name='ContentType' />",
"<FieldRef Name='PONumber' />",
"<FieldRef Name='EndUser' />",
"<FieldRef Name='ProjectManager' />",
"<FieldRef Name='Purchaser' />",
"<FieldRef Name='Title' />",
"<FieldRef Name='ID' />",
"<FieldRef Name='EncodedAbsUrl' />",
"<FieldRef Name='FileLeafRef' />",
"<FieldRef Name='FileRef' />"
query.Query = strQuery;
query.ViewFieldsOnly = true;
contentiterator.ProcessListItems(somList, query,
delegate(SPListItemCollection listItems)
itemcoll = listItems;
if (itemcoll != null)
if (itemcoll.Count > 0)
dtResults.Merge(itemcoll.GetDataTable());
}, null);
return dtResults;
catch (Exception ex)
throw;
In the Query, we have added Index to Columns used in Where Clause
Condition.
FYI, In Production environment, Document Library Contains 60,000 Items. Administrator not ready to increase List View Theshold Limit more than 10000.
Please assist on this. Waiting for your reply...
