This package which is a child package has been running successfully for quite some time now. All of a sudden we are getting these intermittant error messages. Does anyone have any ideas what to do or check for? thanks =========================== Error portion Error: 0xC0047012 at CF-DFT Oracle Sales Fact, DTS.Pipeline: A buffer failed while allocating 100483760 bytes.

Most probably the SSIS process has run out of virtual memory. Apparently, there is plenty of physical memory on this machine (8Gb?), but the amount of virtual memory a single process can use is usually 2Gb, and it seems like there is no more space for 100Mb buffer that package tries to allocate. Without knowing the package content, it is hard to give any advice how to fix it. But some possible ideas: I suspect you've increased default buffer size,set it back to ~10Mb default Switch to 64-bit OS (pretty radical, is not it?) Add /3Gb switch to boot.ini Split the package (if it has multiple data flows) into sub-packages and execute them with out-of-process option in Execute Package Task (so that each sub-package gets its own VM space) Install SP1 - although I don't remember if there were any specific changes in memory handling

Thanks for the information. I'll review this when I get back to work. We currently design all our ETLs to be designed in a parent/child pattern where there is one driver that calls all the child packages. We can't change/convert to 64bit just yet but it's good to know that it's a plausible option in the future. I'll have to check on the /3gb option. I know we haven't done that in this case. SP1 didn't appear to have much of value for us so we haven't even considered it. However, this might be a reason to take a more detailed look at it. I'll check on the buffer size. I just don't remember if it was changed. However, I do suspect it was increased to try to get better performance. John

Using parent/child pattern in this case is a good idea. Note that by default, Execute Package task executes child packages in the same process as parent packages. You may get more (total for all packages) usable memory on 32-bit machines if you change it to execute child packages in a separate processes.

I made the change to have the child packages run in their own memory context and it appears to be working for now. I'll keep my fingers crossed. thanks for the help John

In my specific case, simply changing the sample size in the "row sampling transformation" which was part of the package sorted this.? It seems I could sample 20Million rows, but cannot do 50mill.

Experiencing same issue, but solved with the help of your bellow comment "I suspect you've increased default buffer size, set it back to ~10Mb default " V-Jai

VJai, how did you decrease the buffer to ~10Mb default i have data flow task component which comprises of a oledb source and a scrip component. The vb code for the script component is as below Public Overrides Sub PreExecute() MyBase.PreExecute() ' ' Add your code here for preprocessing or remove if not needed ' End Sub Public Overrides Sub ProcessInput(ByVal InputID As Integer, ByVal Buffer As PipelineBuffer) While (Buffer.NextRow()) Dim newFileName As String Dim destFilePath As String Dim destFileName As String Dim delimiter As String Dim indx As Integer newFileName = Path.GetRandomFileName() destFilePath = "dir\struc" destFileName = Path.Combine(destFilePath, newFileName) writeFile = New FileStream(destFileName & ".dat", FileMode.Create, FileAccess.Write) sw = New StreamWriter(writeFile) delimiter = Buffer(1).ToString() sw.Write(Buffer(0).ToString() & delimiter) For indx = 2 To Buffer.ColumnCount - 1 sw.Write(vbCrLf) sw.Write(Buffer(indx).ToString() & delimiter) Else If (Buffer.IsNull(indx)) Then sw.Write(delimiter) Else sw.Write(Buffer(indx).ToString() & delimiter) End If End If Next sw.Close() End While Buffer.Dispose() End Sub Public Overrides Sub PostExecute() MyBase.PostExecute() sw.Close() writeFile.Close() End Sub i get the belwo warnings everytime i run the package for all the output values, the problem is i cant remove these output as my script task is consuming them.
