Creating MSXML2.DOMDocument60 and running out of memory

I'm iteratively loading xml documents into a the object oInstance, searching for data in the docs then repeating.

The code that loads the documents is:
Code:
Private Sub LoadInstanceDocIntoMemory(COUNTER As Long)


    If ActiveCell.Offset(COUNTER, 0) <> "" Then
    
        Set oInstance = Nothing
        Set oInstance = New MSXML2.DOMDocument60
        oInstance.async = False
        oInstance.validateOnParse = False
        oInstance.Load "http://" & ActiveCell.Offset(COUNTER, 0)
    
        If oInstance.parseError.ErrorCode <> 0 Then
            MsgBox "Error loading file: " & vbCrLf & vbCrLf & _
                "File URL: " & oInstance.parseError.URL & vbCrLf & _
                "Error Code: " & oInstance.parseError.ErrorCode & vbCrLf & _
                "Error Description: " & oInstance.parseError.reason & vbCrLf _
                , vbCritical
        End If
    
    Else
        Set oInstance = Nothing
    
    End If


End Sub

After about a while I get an out of memory error and I can see that the memory allocated to Excel is large at about 300k. I hit Debug, then Run and got the same error after about the same number of iterations when the Excel memory was at about 500k.

I'm wondering what I'm not doing to clear memory that I should.

I set oInstance to Nothing at each iteration but I'm also creating a New MSXML2.DOMDocument60 at each iteration. Is this the correct methodology or should I 'clear' and 'reuse' an existing MSXML2.DOMDocument60.

Let me know if I'm not being clear enough, I'm new to doing things with XML so I don't know what's needed to help trouble shoot.

Any help or references is appreciated.

Select range and press Ctrl+Shift+3 to format cells as date. (Shift 3 is the # sign which sort of looks like a small calendar).
