Hi Jochen, thanks for your reply.   I set some console messages up so I can see what part of the code it's failing at.  I put one of these in at the start of the agent run however it's not even getting that far before it falls over.  I think it's falling over when it gets to the dim statements.

Dim session As New NotesSession

Dim db As NotesDatabase

Dim matrix As Variant

Dim mail_doc As NotesDocument

Dim mail_body As NotesMIMEEntity

Dim keywords_db As NotesDatabase, payrollProjectsDB As notesdatabase

Dim keywords_view As NotesView, payrollProjectsView As NotesView

Dim stream As NotesStream

Dim payroll_doc As NotesDocument, payrollProjectsDoc As notesdocument

Dim message As String

Dim testDate As Variant

Dim test As variant

Dim dayHeader As boolean

Dim i As Integer

MsgBox "1111"

Dim payRunView As NotesView

Dim PayRunDoc As NotesDocument

Dim payRunTasks(9) As String, payRunLabels(9) As String

Dim test1 As Variant, test2 As Variant, test3 As Variant

Dim earliestDate As Variant

Dim lateString(0 To 200,0 To 5) As Variant, services As String

Dim count As Integer

Hi there, found it was and it still doesn't make sense!  it had problems with

Dim lateString(0 To 200,0 To 5) As Variant,

once I changed it too

Dim lateString(0 To 200,0 To 5) As String

it worked.  The variant version worked on my domino 8.5 server however seems to be causing an out of stack issue on my Domino 9 one, is this a known issue?? 

didn't know redim put it in a different place....good tip that!  I usually use redim but I knew what size I wanted the array matrix to be so just stuck it in the dims.  I usually build there 2d arrays to take a variety of data types and it works normally......I'll do some little tests on the redim version.

Thanks again for you input on this.
