Hi JJoshJL,

This may have to do with concurrent connections.  This topic is not completely clear to me, but, we might be able to modify your logic to overcome the problems you are having.

If during processing of the qr results, you "collect" the items you want to update inside the loop and then do a batch update outside the loop you may be able to overcome the problem.

'Set up your array of updates here
Dim conacc(0) As sforce.Assets__c()
While bContinue
For b = 0 To qr.records.GetUpperBound(0)
Dim l As salesforce.Assets__c = CType(qr.records(b), salesforce.Assets__c)
assetid = l.Id
accountid = l.Customer_Number__c
soql2 = "select OwnerId from account where id = '" & accountid & "'"
Try
Dim qs As salesforce.QueryResult = Nothing
Binding.QueryOptionsValue = New salesforce.QueryOptions
qs = Binding.query(soql2)
c = 0
If qs.size > 0 Then
For c = 0 To qs.records.GetUpperBound(0)
Dim m As salesforce.Account = CType(qs.records(c), salesforce.Account)
userid = m.OwnerId
Next
End If
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Dim updowner As New salesforce.Assets__c
updowner.Id = assetid
updowner.OwnerId = userid
'add the updowner to your update array
conacc(conacc.GetUpperBound(0)) = updowner
'check to see if we are at the end of this query batch, and if not
'add another element to the end of the array is anticipation of the next loop
If b < qr.records.GetUpperBound(0) Then ReDim Preserve conacc(conacc.GetUpperBound(0) + 1)
'Echo you progress to the console
Console.WriteLine(b & ":" & l.Id & ":" & accountid & ":" & userid)
Next
If qr.done Then
bContinue = False
Else
qr = binding.queryMore(qr.queryLocator)
End If
End While
'Not that we have created an array of items to update,
Dim sr() As sforce.SaveResult = binding.update(conacc)
'update the whole batch and check the results.
For i As Integer = 0 To sr.GetUpperBound(0)
If sr(i).success Then
Console.WriteLine("asset updated: " + sr(i).id)
Else
Console.WriteLine("error updating asset: " + sr(i).id + " - " + sr(i).errors(0).message)
End If
Next
