Out Of Memory Exception - Loading Datatable

Question

I am trying to create a datatable and load a single row in to the datatable. I am using this datatable as table type parameter. But this method is enclosed in a ParallelProcessor. Some records are being updated but for some I get the below Out of memory exception.

ParallelProcessor.EnqueueAsync(() =>
{
public DataTable Getrecords(List<testData> testData)
        {
            DataTable table = new DataTable();
            table.Columns.Add("ID", typeof(int));
            var data = testData.Select(x => x.ID);

            foreach (var item in data)
            {
                DataRow dr = table.NewRow();
                dr["ID"] = item;
                table.Rows.Add(dr);
            }
            return table;
        }
});
ParallelProcessor.WaitForQueueCompletion();

Below is the error which I get for some records

System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. at System.Data.RBTree1.TreePage..ctor(Int32 size) at System.Data.RBTree1.AllocPage(Int32 size) at System.Data.RBTree`1.GetNewNode(K key) at System.Data.DataTable.SetNewRecordWorker(DataRow row, Int32 proposedRecord, DataRowAction action, Boolean isInMerge, Boolean suppressEnsurePropertyChanged, Int32 position, Boolean fireEvent, Exception& deferredException) at System.Data.DataTable.InsertRow(DataRow row, Int64 proposedID, Int32 pos, Boolean fireEvent)

It is perfectly working on some environments.
